DIY Guitar

I have had some experience "fooling around" with a home made guitar. My attempts were with alum. "L" bar riveted together and using bicycle s/s spoke nipples and pieces of s/s spokes as the tensioning device. Problem with alum. is is that it is soft. After a few months the frame warped-- all those strings under tension probably did it. But then, if alum is soft, the rivets are even softer, and when I tightened up a few wires one fateful day, I ended up shearing off the heads of the rivets.
Thing is, in order to cut a slab of ganache, the wires have to exit the slab to make a clean cut. This means the wires have to end up below the slab when the cut is finished. To do this, I took a large nylon cutting board, and cut a series of 1/8" deep x 1/8" wide grooves in it with a table saw. This does the trick, but now I had to anchor and hinge the frame to the base, as any shifting when I pushed the frame down would make for messy cuts. And, a lot of crud gathered in the grooves of the cutting board. Probably close to 100 hours of farting around and "Wile E. Coyote Back to the drawing board" moments fooling around with this contraption, and now it sits in the attic of my garage.
I do 3 slabbed ganache varieties at work. What I use is a cutting wheel. At dollar stores, I buy a dozen s/s pizza wheels, usually 3" dia. I cut out the rivets, throw away the handles, and mount the wheels on a length of redi rod (all-thread rod) I have a lathe at home so I turn sections of hollow oak, cut them to 7/8"lengths, and space the wheels with these, make some handles, and cap off both ends with acorn nuts. Matfer has a version of this, which I un-shamefully ripped off, the 2005 catalouge listed it for over 300 USD. A picture is worth a thousand words...
After I pour out the slab, I wait until semi-firm, not fully crystalized, and then paint on a top layer of couverture, flip it over, then paint on a bottom layer. I put my contraption in the oven for a minute or so and then cut through the slab in strips, then in squares. Works quite well , and I spent far less than 10 hours making the thing.........
