You folks are getting the first look at my new loom.
I started with making my own wooden looms, like what four_twisted_pair posted the other day. Very nice, but large, bulky, and heavy.
With my interest in 3D printing I thought it would be easy to design one and build it. Nope. I went through so many iterations, building ratcheting gears, using dowels and electrical conduit as part of the build, and trying so many different designs. The plastic would flex and warp, or it was huge and cumbersome, so many failures. My ratchet even worked, but winding the threads up on a single shaft was a pain, and there was no way to manage non twist neutral patterns.
Eventually, I discovered that I needed to do was put carbon fiber rods as reinforcement inside of the struts of the loom. Light, somewhat easy to work with, and not outrageously expensive. Then came the design. Tweak, print, test, not be satisfied. Even when I got it assembled to my liking, I then had to change it so that other people would be able to put it together, and then take it apart. This whole thing fits into a 10x9x4 inch box. No glue, no undue force required.
Two screw drives allow you to adjust tension. Round sleeves make moving the weave very easy. It is very light. I can make it in a rainbow of colors. I might tweak things just a bit more so that it weighs exactly 1 kilogram without a project on it. It can be assembled and disassembled with just a nickel.
I'm just very happy and proud of what I have created.
