Here are pictures of the warping mill that I built. The pictures show it set up and folded up. Each full turn is 2 yards. You can't see the handle because it's on the right, but it's a Leclerc handle from a loom that I used to have. The wooden circular pieces on the left act as a brake. I can let it turn freely by opeing up the thumb screw, or make it not move at all by tightening the thumb screw. I put a full rectangular base on it because some of the places I set it up are small, and this way it can be only a little more than half on a table and still work once it's clamped down. I have pegs on the wall that I hang it from when it's not in use.
My next project is a warping trapeze for my Macomber.
