The slab protrudes into three dimensional space, referencing the negative as if to say that came from this, but this is bigger than that, so that other part must have gone somewhere below this. The trace only lasts for several weeks until the dark negative, which is merely a thinness of the surface, normalizes to the rest of the frozen thickness surrounding it. But until that point the ice object narrates a cause and effect; cut, shift, and freeze. The inextricably linked relationship between solid and void, or positive and negative, and even light and dark, engages in a spatial exchange that goes beyond the surface into a space that is obscured otherwise. The space it references operates as an abstraction within abstractions. The ice object is an abstraction of water, manipulated in such a way that it obfuscates itself and creates a third abstraction of an inaccessible space. And through this abstraction of a subterranean space, an other space is created in the mind of the subject. <br /><br />It can be deduced that if the shape of the negative is twice as large as what reads as the positive, then we see only half of the positive above the surface, and can assume the other half is below the surface. And knowing that what we see is a chunk of ice bearing the same properties as the shape of negative (ie: continuous, uninterrupted, and coplanar), the chunk must do the same thing where we cannot see it. We can assume the ice object interrupts the space of the water below in the same manner as it does the air above. However the image of the ice as it appears to our eyes does not follow our systematic logic, and instead defies what we know of coplanar surfaces, and creates the effect of gently intersecting planes, which is an effect of reflectance through one medium to another or air to water. This is one read of what appears to be vs. what is. <br /><br />The second read I would offer is the condition of the ice cut after several weeks –when the negative equalizes with the rest ice. No longer is there any trace of the positive intersecting with the negative, as the negative returns to an opaque gray, blending with the larger body of ice. What we might recall from science class is that the density of water is constantly oscillating as it narrows down to the point of freezing. Warm water rises to the surface (because it is less dense), cools from the air, and then falls back down to the lower depths where it is re-warmed. This process continues until the entire body of water reaches 4C, at which point the density of water reverses, or in other word the colder it gets the less dense it gets, and therefore stays on the surface, ultimately becoming ice. As the cold temperatures persist the ice freezes more, thickening the hardened surface. <br /><br />But the water below is still 4C and so then it must be assumed that the negative protrusion of the ice object from above is submerged in water that is actually higher than the freezing point, and subsequently melts away. The condition that had previously been imagined below the surface is merely a spatial abstraction that does not exist. Yet the precision in which it describes space through an indexical relationship, and the image the subject can construct mentally is vivid enough to argue that it actually does exist, insofar as it elicits the same response from each subject. The fact that the subterranean ice object is merely made up is irrelevant as it carries with it a spatial experience as vivid as the real thing.marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com1tag:blogger.com,1999:blog-1264382461774105262.post-44661056671084539792010-03-10T09:43:00.000-08:002010-10-17T01:37:32.575-07:00Sugar Season<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2hbPGmEtIFepB8yQ23ZTKbwSYCVbg1duXytFjlhj2muSrAifq4eE8Yki0jN_XE9SF532klpd77_5oTuElwoopivNcj0sniiD2S5tF-6Paurx2KSU1FqFoo5P9EGLQiPBeJni0QzJ09l0/s1600-h/IMG_6911.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2hbPGmEtIFepB8yQ23ZTKbwSYCVbg1duXytFjlhj2muSrAifq4eE8Yki0jN_XE9SF532klpd77_5oTuElwoopivNcj0sniiD2S5tF-6Paurx2KSU1FqFoo5P9EGLQiPBeJni0QzJ09l0/s400/IMG_6911.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5447066722021451778" /></a><br /><br />Since I stopped working on the ice cuts I've taken up a small maple syrup operation in my front yard. I have two decent sized red maples and few sugar maples, three of which I've tapped. I purchased the taps for $3 at the Dexter mill and cut holes in milk jugs as collection buckets. Tapping the trees was pretty straight forward, drill a 2 inch deep hole at a slight upward angle into the trunk of the tree about 3 feet from the ground. Next, pound the tap into the hole and attach the collection jug, and the sap literally starts flowing (or dripping) at the rate of leaky faucet. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3SKORWXoWnIU3nw0onAEYxpxg2e3ylLRgjOC-Tsh1PJg2tpRbN9MtCHUr4kIot9t8vIvsQWXxc3iF9crlMTHwxxMRF-RMhllDSJZgKcn5xCnEszSAd3soDoGJ55vqMxM8k-DCQjNfRG8/s1600-h/IMG_6912.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3SKORWXoWnIU3nw0onAEYxpxg2e3ylLRgjOC-Tsh1PJg2tpRbN9MtCHUr4kIot9t8vIvsQWXxc3iF9crlMTHwxxMRF-RMhllDSJZgKcn5xCnEszSAd3soDoGJ55vqMxM8k-DCQjNfRG8/s400/IMG_6912.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5447067472900585730" /></a><br /><br />The most peculiar thing about this process is that the temperature must get down to freezing at night and go above freezing in the day.

The weather snapped again, getting very warm during the day, and I was flowing about a gallon and half at its peak. So far I think I've collected 8 + gallons. Last weekend I boiled down a batch on a makeshift fire pit in my yard. Apparently an open fire imbues a smoky flavor in the syrup that is said to be the best. Okay, wood fire it is. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj70mUNU9o3O5UoGSz_jF7LOcjUBbTU1aMy_Q6_hnz3ivkTLwwJ8q_4ryhQO1-m6AojY1vTivPE99PTGLWGuqmbmfp2Bw4lpAvozqpqTIWH2NYwt3ugc-q8jmNg5hv-uYDRfOJdIMz0oKM/s1600-h/IMG_6956.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj70mUNU9o3O5UoGSz_jF7LOcjUBbTU1aMy_Q6_hnz3ivkTLwwJ8q_4ryhQO1-m6AojY1vTivPE99PTGLWGuqmbmfp2Bw4lpAvozqpqTIWH2NYwt3ugc-q8jmNg5hv-uYDRfOJdIMz0oKM/s400/IMG_6956.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5447068790155081810" /></a><br /><br />This took a very a long time, and required constant maintenance -lots of little pieces of wood were added to keep the flame hot. Luckily my roommate Erik chopped lots of wood throughout the day keeping a steady supply on hand. If the fire got down to just coals, the sap would only simmer. The sugar content in sap is about 2-6 % depending on who you ask. Boiling down 4 gallons took almost 12 hours, which is hideous compared to the rate at which small syrup operations evaporate their sap (hundreds of gallons per hour). By 10:30p the sap was getting darker colored and was quickly reducing down into syrup. I brought it inside to 'finish' it on the stove, which requires monitoring the temperature with a candy thermometer until it reaches 104 C, which is above the boiling point of water. This number tells you that your sugar content is correct and the syrup is done. One could continue boiling it, and would end up with maple sugar. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPuT0Zxzz-BO8Ro_gYJ70cWwP8S8YMuScJzj_CgGGQOr04vWketll3ZR7cJuAHPK_DRgnjb8tzKngvTv6uPz2JEhqJ2d9cfZ5DpndsiC0v_uyaZbvLgm7dkZNnG6HH4k14AP4HEeatjZM/s1600-h/IMG_6960.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPuT0Zxzz-BO8Ro_gYJ70cWwP8S8YMuScJzj_CgGGQOr04vWketll3ZR7cJuAHPK_DRgnjb8tzKngvTv6uPz2JEhqJ2d9cfZ5DpndsiC0v_uyaZbvLgm7dkZNnG6HH4k14AP4HEeatjZM/s400/IMG_6960.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5447070802494729730" /></a><br /> <br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjQp-CVrWhcDgo4Gy8jW22872HRPl2IQaJC30AoOmW18vzWDCOxxX9odVbA9MgTipB9Kjr52z_Mrcg83J6i0adgxKa18K56jKDS586GP5Dv6PzA4fh1IWngkdlAiyx_uFhs9q3d73RB6MY/s1600-h/IMG_6961.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjQp-CVrWhcDgo4Gy8jW22872HRPl2IQaJC30AoOmW18vzWDCOxxX9odVbA9MgTipB9Kjr52z_Mrcg83J6i0adgxKa18K56jKDS586GP5Dv6PzA4fh1IWngkdlAiyx_uFhs9q3d73RB6MY/s400/IMG_6961.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5447070120615571954" /></a><br /><br />The syrup tasted very good, and you could definitely pick up a smoky flavor, which was actually quite nice. To be methodical, the next day I boiled down the other half of my sap on the stove, just to be sure there was a difference between open fired syrup. This was way easier because you could forget about monitoring the flame, although it took nearly the same amount of time.

I actually don't like the shape of a traditional syrup bottle, but they only cost about $1 each. Shipping was more expensive than the bottles. I'm going to design some labels for the bottles, and begin speculating on this project at the scale of a neighborhood, and then the city of ann arbor, which by the way maps every single tree on every street, and all the trees in the parks thanks to the forestry department. Of these trees, 37% are maples.

Now the ice is melting along the fractures and has taken on a lumpy, jagged look.

The temperatures are hoovering around freezing in the day and only getting down to the 20's at night. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjloLHUQP1XLTjhI4wDImaq91w_MM0wc8rHWlNoWH1Ody_n2WdmJrAinVJtsywL3PEuCiJubrKxCOHIV20JbIfU5sMF2qdQJgRcgLmZ-MBSsYJbkUbrKRDg-u0oPBWEWQaYE_dIlTepigY/s1600-h/IMG_6924.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 240px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjloLHUQP1XLTjhI4wDImaq91w_MM0wc8rHWlNoWH1Ody_n2WdmJrAinVJtsywL3PEuCiJubrKxCOHIV20JbIfU5sMF2qdQJgRcgLmZ-MBSsYJbkUbrKRDg-u0oPBWEWQaYE_dIlTepigY/s320/IMG_6924.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5441858965198660914" /></a><br /><br />I took apart the big gantry crane, and hauled it on dry land.

I still have plenty of work to do on the ice saw design, and I just tried waterJET cutting a couple slabs of ice I cut from some of the older ice-cuts that are still standing. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiE5a_BJ-zMq48YUocYuYX6LymXuJWFKqTKMv2Tz31DWg3sVdAWhyZaBUTEFGPIHw6XREn0udrxHrQUDROlfzkimKTh3PeC69rGOfVp384f_gFlkvZKUQRY-vHqJVPlyA8kF0jJ4DUxEjM/s1600-h/IMG_6927.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiE5a_BJ-zMq48YUocYuYX6LymXuJWFKqTKMv2Tz31DWg3sVdAWhyZaBUTEFGPIHw6XREn0udrxHrQUDROlfzkimKTh3PeC69rGOfVp384f_gFlkvZKUQRY-vHqJVPlyA8kF0jJ4DUxEjM/s320/IMG_6927.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5441859663573979746" /></a><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJMisY6HTj6YhyzzRvWMiC7lVzFx8f9N6jcyD0Gfl3N_0wic52FMcegIt8ewAHZU0YntZLAuab2lVwVcKEBg3m3g639Caw41Et2bUspEzA6MQtyrhXQANh-ov-_dypwiL3pHJx9hNrURk/s1600-h/IMG_6932.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJMisY6HTj6YhyzzRvWMiC7lVzFx8f9N6jcyD0Gfl3N_0wic52FMcegIt8ewAHZU0YntZLAuab2lVwVcKEBg3m3g639Caw41Et2bUspEzA6MQtyrhXQANh-ov-_dypwiL3pHJx9hNrURk/s320/IMG_6932.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5441860031362552994" /></a><br /><br />The waterJET cut through the ice effortlessly, but overall the process didn't work very well. When the waterJET would begin to cut by piercing the material the ice would usually fracture from the force of the jet. I tried adjusting the pressure from 60,000 psi to 15,000 psi, but the results were basically the same. All in all, it does work, however melting is of course a huge factor. The water coming out of the jet nozzle is very hot from the intense pressure. That and the room temperature quickly works against you. Routing the ice would probably be a better option, but I wouldn't be allowed to put a big, melting block of ice on the router table.marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com1tag:blogger.com,1999:blog-1264382461774105262.post-52160316104871339412010-02-20T21:09:00.000-08:002010-10-17T01:37:32.580-07:00Ice Cut #6<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/P-5JKa74Tpg&hl=en_US&fs=1&rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/P-5JKa74Tpg&hl=en_US&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com1tag:blogger.com,1999:blog-1264382461774105262.post-76648311798097641602010-02-20T21:00:00.000-08:002010-10-17T01:37:32.582-07:00A video to meditate on....<object height="340" width="400"><param name="movie" value="http://www.youtube.com/v/wzbjgds4RGA&hl=en_US&fs=1&rel=0"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/wzbjgds4RGA&hl=en_US&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" height="340" width="400"></embed></object>marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com0tag:blogger.com,1999:blog-1264382461774105262.post-22607940540478718372010-02-20T20:51:00.000-08:002010-10-17T01:37:32.584-07:00Lock Mechanism 2.0<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhUPYRNXGEeQVFDN4xrYp0Vg2Wr5FYP5ntWNXPdP5y8b7Ls2BB5X18qXodokAre2jAgLSdoas4gXOfH5yP96oEyBLRqDu9QEcvmI88lJ-HOHylPoqEQbDN1rmUKxq9KPjC0WaLYjZv-JX8/s1600-h/IMG_6905.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhUPYRNXGEeQVFDN4xrYp0Vg2Wr5FYP5ntWNXPdP5y8b7Ls2BB5X18qXodokAre2jAgLSdoas4gXOfH5yP96oEyBLRqDu9QEcvmI88lJ-HOHylPoqEQbDN1rmUKxq9KPjC0WaLYjZv-JX8/s320/IMG_6905.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5440555206699597986" /></a><br /><br />This is the new lock mechanism I made using 1/2" thick steel, cut on the waterJET, and TIG-welded together. It's about 3 times as thick as my last lock, which failed under heavy load (see image below).

Nothing very impressive happened, for the following reasons:<br /><br />-the lock mechanism is mangled from the last cut<br />-the piece of ice broke....almost the same way one would snap a key off in a lock<br /><br />However I did take some interesting photos of the effects that occur with the water and ice as it toggles between 2D and 3D. And for whatever reason there was lots of pressure under the ice this time, which spewed about 2-1/2 inches of water on the surface once I drilled through to connect the chain. This made a nice glassy surface between the the top of the ice, the hole, and the floating pieces. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj_T6G4KN5IAam20-KKwcxxOwYxJA6vjG80skG75Q3RdexTbI0cq9bn5g2SKR_0JubzKJDah6WJe18QTFMzDfPrg8idHOObYYC0o341bfk680s0D8PgUu1HdWFk7GLhy6memuYOsN97Xws/s1600-h/IMG_6859.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj_T6G4KN5IAam20-KKwcxxOwYxJA6vjG80skG75Q3RdexTbI0cq9bn5g2SKR_0JubzKJDah6WJe18QTFMzDfPrg8idHOObYYC0o341bfk680s0D8PgUu1HdWFk7GLhy6memuYOsN97Xws/s400/IMG_6859.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5438551750224852514" /></a><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPWPhNQbo9p_5xxQzhmMnyMpHDgtkqP8Mh1Faha39f5vmObKQIqH-VjuAQCifY5E8T03tb3wtEC5c255J9MCoucdjN_YxQSYqQx9kj8vdF4t8KbdK8tDbqkYAKmeaSw6NqY0q-gA_3cKQ/s1600-h/IMG_6857.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPWPhNQbo9p_5xxQzhmMnyMpHDgtkqP8Mh1Faha39f5vmObKQIqH-VjuAQCifY5E8T03tb3wtEC5c255J9MCoucdjN_YxQSYqQx9kj8vdF4t8KbdK8tDbqkYAKmeaSw6NqY0q-gA_3cKQ/s400/IMG_6857.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5438552224836381602" /></a><br /><br />My plan now is to spend some time making a new lock that will work consistently.marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com2tag:blogger.com,1999:blog-1264382461774105262.post-71195467970464267512010-02-13T10:45:00.000-08:002010-10-17T01:37:32.588-07:00A little success...<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinUy0vUi0O-NNKlL68Ha_P8ENEaXqF96aBADuIPUsVK2NO9r5SKnZGGC12Gsc1MRB4zVoJ7OxK47A9yj9_lAkzFd4L-50hFKIbemHes3G6NXBPDQfH1NB3edkzO0zFHw-LR6AqyDBlPEE/s1600-h/IMG_6700.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinUy0vUi0O-NNKlL68Ha_P8ENEaXqF96aBADuIPUsVK2NO9r5SKnZGGC12Gsc1MRB4zVoJ7OxK47A9yj9_lAkzFd4L-50hFKIbemHes3G6NXBPDQfH1NB3edkzO0zFHw-LR6AqyDBlPEE/s400/IMG_6700.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5437801503826674674" /></a><br /><br />These are images of cut #4 on the next day, still standing, which proves the through-bolt method works well. I was incorrect in thinking that the locking mechanism failed. It did work, but is quite mangled as a result. Going forward my strategy will be cutting irregular shaped pieces (think L-shape) and letting part of the ice rest on the top surface in addition to a chunk still in the water. Another option is a "lasso-method", which would require someone to connect a chain (looped over the header of the gantry) to the slab of ice as it reaches the top of the gantry crane. I think this would actually be doable since the winch is moving very slow as the slab is pulled up high. <br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJYvbjrmYBK1zFFxKNMoc3_UZhnarkgT_PB6f2DwX2xnFzv5cnYBQhJ-GFjiK5XxxqvpeshOkuwJEipYLCcC-B4y-KIh0HvGIbAXeN5MCpc-D2p9e3RqFvIHgL5nf4cogV6HOlfxbkcoI/s1600-h/IMG_6704.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJYvbjrmYBK1zFFxKNMoc3_UZhnarkgT_PB6f2DwX2xnFzv5cnYBQhJ-GFjiK5XxxqvpeshOkuwJEipYLCcC-B4y-KIh0HvGIbAXeN5MCpc-D2p9e3RqFvIHgL5nf4cogV6HOlfxbkcoI/s400/IMG_6704.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5437801802225730610" /></a>marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com0tag:blogger.com,1999:blog-1264382461774105262.post-46608960224912677712010-02-07T20:31:00.000-08:002010-10-17T01:37:32.590-07:00Fourth Cut<object width="560" height="340"><param name="movie" value="http://www.youtube.com/v/t8JV-E_PnKU&hl=en_US&fs=1&rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/t8JV-E_PnKU&hl=en_US&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="460" height="340"></embed></object><br /><br />The locking mechanism sucks. I think the problem is that I integrated it within the winch itself, so when I load the winch with 2000 lbs of ice the internal stresses are so great it binds the moving parts. My plan is to add an external 'clicker' that will bolt to the gantry crane, and be independent of the winch, but still lock the spindle. <br /><br />Cut #4 was pretty successful. In addition to the typical lag bolts I use, I put two through bolts in the slab with butterfly clips on the end, which keeps it from pulling back out. Although the winch lock failed, I think the slab was cut long enough to bottom out, stopping the free-fall. <br /><br />I'll check on things in the morning and see if it held up. I'm now trying to time my cuts towards late afternoon, so the evening drop in temperature works to my advantage. The sunshine causes the bolts to pull out more easily. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh27BnvVSuLEHka2wEDsScKB6GYt6gFdNa9ooK2Y6tfhdRyO8ag58OQgl1md0VA3mCXOFQgbfHp2IMbLYhjOTRVpJb3sXI1V8DfZOzZ3b79uFd8_OTrPVH-5BMcrdO8zBkT3-QatKgs4Xc/s1600-h/IMG_6692.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh27BnvVSuLEHka2wEDsScKB6GYt6gFdNa9ooK2Y6tfhdRyO8ag58OQgl1md0VA3mCXOFQgbfHp2IMbLYhjOTRVpJb3sXI1V8DfZOzZ3b79uFd8_OTrPVH-5BMcrdO8zBkT3-QatKgs4Xc/s400/IMG_6692.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5435729604651075218" /></a><br /><br />This is a photo I took of my last failed attempt.

The lag bolts had come loose, which is now another wrinkle to iron out. <br /><br />I decided to approach cut #4 with a different strategy, cutting a long and narrow chunk of ice hoping that it would sink into the bottom of the pond, relieving the load put on the lag bolts while waiting for everything to re-freeze. I don't have video of this because I filmed from the beginning and this piece took twice as long to cut, so my memory card filled up at some point during the process. I was able to get the piece of ice almost 9 feet out of the water, but the locking mechanism had failed after Cut #3, and the winch free-wheeled back down, ultimately breaking the slab. But a small chunk remained, so I left the rig hooked up to see what happens over night. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgoywNCL2vx1wPRPwRasTG4ifjPrR0B2ylNJBq6E_Wb-K_Kr89sr6Ai76OSNVVPQ9t5cyYpgnexN57Yn3aSLUJLqUtfnkwNvymrD2Fv2UMvoHyPONNq8dai_QMwCQiscM_CgcY4eFmA92M/s1600-h/IMG_6672.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgoywNCL2vx1wPRPwRasTG4ifjPrR0B2ylNJBq6E_Wb-K_Kr89sr6Ai76OSNVVPQ9t5cyYpgnexN57Yn3aSLUJLqUtfnkwNvymrD2Fv2UMvoHyPONNq8dai_QMwCQiscM_CgcY4eFmA92M/s400/IMG_6672.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5435183265452184194" /></a><br /><br />The slab broke into several pieces, and I took some interesting photos of the various chunks interacting with each other.

I finished it with only a few hiccups, and was eager to test it out. I also decided to make a big purchase and buy a stihl chainsaw after the problems I had with the one from lowe's (which they took back, no questions asked). <br /><br />The ice on the pond is doing strange things. Large cracks (as in up to 1/4") are forming throughout the surface, and it's happening in real time, like a glacier on fast forward. At first it's alarming and it sounds like you're going to fall through, but considering how thick the ice is there is no danger. The noises range from typical crrracks, to odd rubber band sounds, and as Jason pointed out on the site visit last friday, like someone getting punched in the stomach.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4yiH6ZPJsQ9az16dRlScHM0znQzbTxt-gHpAYPMJfksO7mbACIXYzWgYcbLC-TaWALN68GaHiNvbYv8eJ6MQ5r82eNzMinWB643ABbBKhvlso2LoJy8S2Xmxw5OrGQrOnj9sbqMSvXiQ/s1600-h/IMG_6599.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4yiH6ZPJsQ9az16dRlScHM0znQzbTxt-gHpAYPMJfksO7mbACIXYzWgYcbLC-TaWALN68GaHiNvbYv8eJ6MQ5r82eNzMinWB643ABbBKhvlso2LoJy8S2Xmxw5OrGQrOnj9sbqMSvXiQ/s400/IMG_6599.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5433845849975408258" /></a><br /><br /><br />The new chainsaw worked pretty well, although it did bog down here and there. Mireille put me in touch with a friend of hers who works on the ice hotel in Sweden, and in the photos it shows him using a huge Stihl chainsaws, the ones that go for over $1000. I settled for the $339 "farm boss", as the salesman assured me it was the most popular all around Stihl. He also showed me a 30 inch diameter tree trunk that he cut through. Okay, sold. <br /><br />Test #2 didn't work out so well, as I'll let the video explain:<br /><br /><object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/-qdbe1lbF88&hl=en_US&fs=1&rel=0"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/-qdbe1lbF88&hl=en_US&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object><br /><br />The failure of the mini-gantry crane was due to a poor connection I made using brad nails. I watched the movie in slow motion the way we did in structures class, and I saw the exact piece that went...and thought about it and remembered 'hey, I never screwed that in'. In part, because I didn't think it was going to be a significant factor in carrying the forces, but once that weak link went, it was all over. <br /><br />One upside to this failed attempt was that I learned just how thick the ice was (I measured 10 inches) so I felt confident about driving my car out on the ice to load up my stuff....confident enough to drive very slowly with the rear hatch and the drivers door open in case I had to jump out, but after five minutes I was very sure about the laws of physics and drove all over the pond, and onto the different washouts from the edge of the gravel pit. And I'm sure my car was the first one to ever do this on the nudie pond, thanks in large part to a small road my Dad put in at the mouth of the pond.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgqzJEXQjUv6mvl9CUUnt_bc6l1w5zwpdsmJJlRPsFrJBCl7qVnwI99XqzPOFw8heAWMWJ7CXGiUoveXb-tuI4-vRKPjp3mlVyanvD58TkLq2sr_rgXPAdRDKxOhRfPMrWJRnCiwGvj6UY/s1600-h/IMG_6634.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgqzJEXQjUv6mvl9CUUnt_bc6l1w5zwpdsmJJlRPsFrJBCl7qVnwI99XqzPOFw8heAWMWJ7CXGiUoveXb-tuI4-vRKPjp3mlVyanvD58TkLq2sr_rgXPAdRDKxOhRfPMrWJRnCiwGvj6UY/s400/IMG_6634.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5433849064319033538" /></a><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQeskum3t1YNKd5LrNFrAll3m42bfvkStJ_88BGm9EyqJXepfU4ptj_V-YW_m-xYUk-bVrquJgIr8JZ09wJvgFgFr7VkGdfb0335HQJqnDmj0SpIRmhk_vi1Lk6zw6kvox2eXVhVu28KQ/s1600-h/IMG_6637.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQeskum3t1YNKd5LrNFrAll3m42bfvkStJ_88BGm9EyqJXepfU4ptj_V-YW_m-xYUk-bVrquJgIr8JZ09wJvgFgFr7VkGdfb0335HQJqnDmj0SpIRmhk_vi1Lk6zw6kvox2eXVhVu28KQ/s400/IMG_6637.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5433849465556556242" /></a><br /><br /><br />I went back to the studio and started ripping the 2x10's down into more manageable sizes, and now I have a bigger, beefier gantry crane that towers 11' high and has stronger connections.

I made another saw on the waterjet, modifying one end slightly to look better with the handle I chose. This saw also has same mounting holes as the handle for mounting the hardware. <br /><br />In thinking about saws, and the possibilities of what it means to obsess over the saw as an aestheticized object, I thought of paint. I wanted to experiment with paint as way to make the saw a saw, while simultaneously as an object that enters into another dialogue with other highly designed objects, and in doing so loses its saw-ness as a functional object, ie: the saw that never makes it off the wall. However it is embedded with a deep narrative behind its function, to which it can certainly perform to its expectations, but may never have to actually be tested as the design will be convincing enough. I thought that painting the saw would confuse the distinction between utility and art object. And certainly the handle enters into this game of oscillation. It sheds superfluous ornament, and unnecessary curves to be a simple handle, yet intentional. There is a single hole for the index finger, referencing a 'trigger', but also providing ergonomic comfort, as a hand gun should. <br /><br /> <a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhNrVMLAdMmgz49zHnA56j7qJ1h1YAi-osD7sjYsXJVTMODsbPW2wrFsBKpv9mSvCWU2X4jBTnnKyqNk_E1YzaBG5StEJX8LXMNPYC-X8-qRZFMHOcjRovrEYU8hH7Gzhd-xA_O6dUlwxg/s1600-h/IMG_0274.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhNrVMLAdMmgz49zHnA56j7qJ1h1YAi-osD7sjYsXJVTMODsbPW2wrFsBKpv9mSvCWU2X4jBTnnKyqNk_E1YzaBG5StEJX8LXMNPYC-X8-qRZFMHOcjRovrEYU8hH7Gzhd-xA_O6dUlwxg/s400/IMG_0274.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5432012806395421746" /></a><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg14IlcWAf9D53daZaatYy0E7b15Yd5A6GxzrfnA1vbRt0NNf5Tx7mVc8nKZIEafjtIGBYXFRlJFKMaNPUhw4rGHtq-z9iYSfZQKmDXrekDDon20F2A9_64joNpP8EKAb-nM00CvikXsD8/s1600-h/IMG_0275.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg14IlcWAf9D53daZaatYy0E7b15Yd5A6GxzrfnA1vbRt0NNf5Tx7mVc8nKZIEafjtIGBYXFRlJFKMaNPUhw4rGHtq-z9iYSfZQKmDXrekDDon20F2A9_64joNpP8EKAb-nM00CvikXsD8/s400/IMG_0275.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5432012991213975538" /></a><br /><br />I was eager to test out the saw after I had finished it, however in my rush to complete it I forgot to make an attempt at tempering it. I had planned on using the oxy-acetelyne torch at school to get it red hot and let it cool again, which would be my best shot at hardening the metal. I called a bunch of metal shops that do heat treating and found one in Pontiac that will temper 4 saws for $28. Anyway, the saw cut like butter until I go about half way down the kiddie pool ice sculpture, when the teeth started to bend ever so slightly at the tips. I'll give a proper heat treating to the first saw I made and see how it performs as a result. That saw will get a t-shaped metal and wood handle, making it a more traditional 'ice saw'. <br /><br />Next project is hacking the winch to make it lock, and building a bigger gantry crane. I loaded up the justy with 2x10s, which barely fit....I had to chop about 3 feet off the ends of the boards so they wouldn't drag on the ground.<br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjygnsxmLPiFw2QNHopIzMHwX7dM23pHsikqrp29r_SSBlNL2ai_gYcvPrBJTlpUqBOV585uHYEfyF0ssDiGwh8Rw73mA9xz6-9e9I_KsTzN0uOKwX9KB_ZPBRv_Gj_ZPBT5o93F3tZC-g/s1600-h/IMG_0271.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 300px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjygnsxmLPiFw2QNHopIzMHwX7dM23pHsikqrp29r_SSBlNL2ai_gYcvPrBJTlpUqBOV585uHYEfyF0ssDiGwh8Rw73mA9xz6-9e9I_KsTzN0uOKwX9KB_ZPBRv_Gj_ZPBT5o93F3tZC-g/s400/IMG_0271.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5432015708092181154" /></a>marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com3tag:blogger.com,1999:blog-1264382461774105262.post-55562602818729617582010-01-28T19:29:00.000-08:002010-10-17T01:37:32.614-07:00Routing the handleI've been working on a few different handle designs in Rhino, and wanted to make them out of a nice hardwood. I bought a 5' length of walnut from the <a href="http://www.recycleannarbor.org/reuse/reuse.htm">re-use center</a>. The wood comes from a group called <a href="http://www.urbanwood.org/">urban hardwood</a>, which is comprised of several small, local saw mills that reclaim trees the city takes down. All of the trees the city takes down are chipped into nothing, which I witnessed first hand when they took down a huge oak tree in my front yard that had died years ago. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlriZXem3EAyHSvq6lau9nQ0waGWQ3PEgT5ldcMoR00ot5NaBmoA_adE35KA1Txc9lu8F4df-ltDP9mHcntup9JeHF-2DlAeew6-L_aaCbt5DbGbYv9B2dFd1yuut4J_D40TdG7AsZBEY/s1600-h/IMG_6536.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlriZXem3EAyHSvq6lau9nQ0waGWQ3PEgT5ldcMoR00ot5NaBmoA_adE35KA1Txc9lu8F4df-ltDP9mHcntup9JeHF-2DlAeew6-L_aaCbt5DbGbYv9B2dFd1yuut4J_D40TdG7AsZBEY/s400/IMG_6536.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5432002330278185122" /></a><br /><br />The board I bought was pretty cheap at only $12.

The jig allows the teeth to uniformly hang over the edge of a 12 degree ramp. Using a hammer, I tapped each tooth until it bends all the way to the mdf. And then flipped the saw over on the other side to repeat the process. It actually worked really well, but this is a long, drawn out method to perform a simple operation. There is a 'saw set' tool that accomplishes the same task. You can buy vintage <a href="http://shop.ebay.com/i.html?_nkw=stanley+saw+set+&_cqr=true&_nkwusc=stanely+saw+set&_rdc=1">saw sets</a> on ebay for under $10. I have a bid on one that should win tonight.

I think I took too much off the teeth, making the tips pointy and weak, but nonetheless I think I (roughly) figured out the technique. The real test will be trying it out on the ice, but since today's high is 43 degrees, that will have to wait to until later in the week when it gets cold again. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjhyfpQrTRMluRyeAnY_7DTjv8B6M-S8naWL7_0CumUfy0EmMdzriOF6LzQeoA0Sx6r-YRPSPLpiSuMDpGg8eJrZ0JE9-JBcW7JvidWm8tmoD3sFsIoPBAKsn56JSzHMExshTobsgriX4Q/s1600-h/IMG_6531.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjhyfpQrTRMluRyeAnY_7DTjv8B6M-S8naWL7_0CumUfy0EmMdzriOF6LzQeoA0Sx6r-YRPSPLpiSuMDpGg8eJrZ0JE9-JBcW7JvidWm8tmoD3sFsIoPBAKsn56JSzHMExshTobsgriX4Q/s320/IMG_6531.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5430408123941594162" /></a><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhL7X-hGXKoBZP-nDuzELtH5hziVmCSgYk6kMpyZtHmKnWldItgln-wGrjpYoVmDRy-JmWZ849OJcutAZvVe71T4bFDmumVr4Vl3cJm1dwEZeKDvqCLciajn6J3YYJe9q6JHDNISh8wvzw/s1600-h/IMG_6534.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhL7X-hGXKoBZP-nDuzELtH5hziVmCSgYk6kMpyZtHmKnWldItgln-wGrjpYoVmDRy-JmWZ849OJcutAZvVe71T4bFDmumVr4Vl3cJm1dwEZeKDvqCLciajn6J3YYJe9q6JHDNISh8wvzw/s320/IMG_6534.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5430408443011909506" /></a>marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com0tag:blogger.com,1999:blog-1264382461774105262.post-10481547421922052742010-01-20T21:35:00.000-08:002010-10-17T01:37:32.621-07:00Winch Locking Mechanism<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1wAltaUfS9uY0ZsZHqd-FvehBpfx9lzEkKRIYqESyHdA5nG9txKXF03n0CiE_JpmnR6jfQ9zOYRswpQMax6I5LQusrzCmLa7oGv1JUSS6D5ElrP6gchw0U4T0Q-IIVrRSJ5Y0euTDPrY/s1600-h/winch_lock.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 395px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1wAltaUfS9uY0ZsZHqd-FvehBpfx9lzEkKRIYqESyHdA5nG9txKXF03n0CiE_JpmnR6jfQ9zOYRswpQMax6I5LQusrzCmLa7oGv1JUSS6D5ElrP6gchw0U4T0Q-IIVrRSJ5Y0euTDPrY/s400/winch_lock.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5429062701734446146" /></a><br /><br />This is my idea for a winch lock to retrofit to my existing ATV winch, which is a fine specimen at only $59 from <a href="http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200381900_200381900">northern tool</a>.

I used digital project to draw the saw so that I can easily go back and change the dimensions by entering a few new parameters. I've also drawn the saw so that the teeth are variable in size and pitch. My thought was to have the saw capable of cutting in both directions, and taking the most bite during mid-stroke. I have yet to test the theory as I've only cut the first version out on the waterjet. I still need to set and sharpen the teeth before I can put it to use.marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com2tag:blogger.com,1999:blog-1264382461774105262.post-74936058833381562682010-01-13T10:41:00.000-08:002010-10-17T01:37:32.628-07:00First Cut<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfgNK_19DpBmSPSYU2804iq4079TFxX2-UJGVtBQ5MIcdJju-h5fr-yryMSKvV43XxUS45k-V1T-FkhCZ2sg67JJzHiLtTbAW28Mmi-UBtT_F97ildDgSIJ002nZgUYuBQLCKfreuVLE4/s1600-h/IMG_6463.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfgNK_19DpBmSPSYU2804iq4079TFxX2-UJGVtBQ5MIcdJju-h5fr-yryMSKvV43XxUS45k-V1T-FkhCZ2sg67JJzHiLtTbAW28Mmi-UBtT_F97ildDgSIJ002nZgUYuBQLCKfreuVLE4/s200/IMG_6463.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5426301479612591938" /></a><br /><br />I made my first real cut on the Nudie Pond (this name dates back to my childhood when the quarry was a popular nude beach destination, and on any nice day one could look over the edge of the gravel pit and see a dozen naked sunbathers.)<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhI5y9u-qSFGcPkeFsQMPTPNzEj-G0YWj6aLbMZ4DSfKSqrf8IMhCukJ9tEjWDZYIl6ikgUQr_e_r590tle8tZpXK_5Z3MI1enTdLL-SLoHvj0fI4nChC1qyM9t00rTf2vZF2Ae9d36hgE/s1600-h/IMG_6451.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhI5y9u-qSFGcPkeFsQMPTPNzEj-G0YWj6aLbMZ4DSfKSqrf8IMhCukJ9tEjWDZYIl6ikgUQr_e_r590tle8tZpXK_5Z3MI1enTdLL-SLoHvj0fI4nChC1qyM9t00rTf2vZF2Ae9d36hgE/s200/IMG_6451.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5426300924206476178" /></a><br /><br />I bought a chainsaw from Lowe's that turned out to be too weak for the job. It kept bogging down in the ice, which was about 7 inches thick. I made the cut roughly 4 x 10 feet, thinking that I would be able to rotate the piece 90 degrees and have it rest on the bottom knowing that the winch would freewheel until it hit something solid. The wooden gantry held up fairly well, but I never could get the slab to stick to the bottom. It was either too deep, or the ice became too buoyent down there, and kicked out. Nonetheless, it was good to see that I could raise a really big chunk of ice from the water, now I just need to resolve the winch issue. I either need to find another winch that has a locking mechanism built into it, or rig up some type of clamping device. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5A509FSFzucw7HpbkWzuP8ZdYDZr8T9deSVXbAmMVnKo6bBJZBDbpMebdDhKKTJQWro7Tw3y9kZCsSbopr4xhSS1w7aeiBZk2cfO9sA3C5Y2BolGOD9ClGY2FF5GmcoQRTYfL7JvYXNw/s1600-h/IMG_6468.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5A509FSFzucw7HpbkWzuP8ZdYDZr8T9deSVXbAmMVnKo6bBJZBDbpMebdDhKKTJQWro7Tw3y9kZCsSbopr4xhSS1w7aeiBZk2cfO9sA3C5Y2BolGOD9ClGY2FF5GmcoQRTYfL7JvYXNw/s200/IMG_6468.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5426301943573751698" /></a><br /><br />I was able to get part of the slab to stick out the water, and by that time it was getting dark. I figured this would be worthy simulation of the real thing, and left it for a couple days. I went back this morning to inspect. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhatkrdlMyTgwkznZgt6IraiQC6lCwLIq_-TNS2CNzBFMUkFtg0f29-3KivUgF9hTC0ITqkXrNK6DgZv2oHBOShN1rq3bgdsTpG3NYcbl5ryBt-HJcWLQB9G-lezLKmXHsfHlscqKDRqRU/s1600-h/IMG_6479.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 150px; height: 200px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhatkrdlMyTgwkznZgt6IraiQC6lCwLIq_-TNS2CNzBFMUkFtg0f29-3KivUgF9hTC0ITqkXrNK6DgZv2oHBOShN1rq3bgdsTpG3NYcbl5ryBt-HJcWLQB9G-lezLKmXHsfHlscqKDRqRU/s200/IMG_6479.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5426302689159485682" /></a><br /><br />It had frozen over very well, and I was pleasantly surprised by some interesting effects going on when the sun illuminated the slab, and the difference in color from the existing ice on the pond and the negative from where the slab was cut. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhREjQARi-r63F__6JgPQlVPwbU4hOLgroU5A1qcl0JTNaAZ_g1xWBMQHAjVZ16PgPEvqik-JDPMJRv5NxFzBsu2PfLMV9cJbsWC-kUoqb6gnVcnrvBIyIaa9HU7R-dc6IEBPkp6jN1Xek/s1600-h/IMG_6482.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 150px; height: 200px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhREjQARi-r63F__6JgPQlVPwbU4hOLgroU5A1qcl0JTNaAZ_g1xWBMQHAjVZ16PgPEvqik-JDPMJRv5NxFzBsu2PfLMV9cJbsWC-kUoqb6gnVcnrvBIyIaa9HU7R-dc6IEBPkp6jN1Xek/s200/IMG_6482.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5426304183033381842" /></a><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN-PVHPUDTePZwvYpVtS8kWWvUpo7UNvpKyZwiW3Q8g-9J9ik0B5nVRrcORtdtoAGqFwWkBAR4gPpjHnKgF17LLl_fNVYaJcrZpJx1sswSa8YuGASxl-0bENYr9NinRbnKRzYvAYVlD5A/s1600-h/IMG_6480.JPG"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN-PVHPUDTePZwvYpVtS8kWWvUpo7UNvpKyZwiW3Q8g-9J9ik0B5nVRrcORtdtoAGqFwWkBAR4gPpjHnKgF17LLl_fNVYaJcrZpJx1sswSa8YuGASxl-0bENYr9NinRbnKRzYvAYVlD5A/s200/IMG_6480.JPG" border="0" alt=""id="BLOGGER_PHOTO_ID_5426304724425969858" /></a><br /><br />Next, I need to build a bigger scaffold so I can handle larger slabs, and figure out the winch / locking mechanism. I should also mention that my the test gantry crane is now frozen in 2 inches of ice. I need to devise a better system for the base, which will always get flooded when I cut a slab of ice. There is quite a bit of water pressure under the ice, and when the slab is liberated from the frozen pond, it sort of pops up dispelling a bunch of water. <br /><br />I'm also working on some drawings for ice hand saws to try out as an alternative to the chainsaw. These will be made using the waterjet cutter at school.marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com1tag:blogger.com,1999:blog-1264382461774105262.post-86196079696648080172010-01-13T10:26:00.000-08:002010-10-17T01:37:32.631-07:00Liberating the Kiddie PoolThe kiddie pool has taken on many roles as a tool to study ice cuts. First it was the lake, when I filled it with water and let an inch of ice freeze over it. I cut a sheet of ice out, rotated the piece, and hung it from a board propped up above the kiddie pool.<br /><br />That test worked. And then it got really cold...single-digits cold. And the whole kiddie pool froze solid. This served as a near-scale model of a slab of ice I hoped to cut from a pond. I built at miniature gantry crane out of scrap wood, and bolted an atv winch to to the cross beam. I was able to successfully lift the chunk of ice in the air, and pull the kiddie pool out. <br /><br />And back to the kiddie pool as the lake: with the frozen chunk lifted up, I refilled the kiddie pool with water, and let it freeze the suspended slab of ice in position. This test also worked. <br /><br />I had two frozen kiddie pool casts bonded together, and wanted to get the plastic pool out. Lifting both of these hunks of ice almost killed the gantry crane, and the weight causes the winch to freewheel back down if it stops getting power (to lift up). I was able to lift everything up and quickly yank the pool out from under the ice. Here is a <a href="http://www.youtube.com/watch?v=MPos8Y-e3Ig">video</a> of it.marcmaxhttp://www.blogger.com/profile/11317903117140342589noreply@blogger.com1
