Rob asked, "Why a trapeze?" I wanted to address some tension problems I have when I wind longer, finer warps. I wouldn't use this for wool blankets, in fact, I don't know if it's going to be any better or not. I just like trying new techniques. Becky's Väv Stuga has a little video that illustrates the trapeze.
I started out with six bouts of 80 threads and used a half gallon milk jug partially filled with water. Each jug weighed ~3.5 lbs. That proved to be too heavy and the warp wasn't moving!
After combining two bouts on each jug things started to move along. So well, in fact, that I forgot to notice that the jugs were at the top. Luckily nothing dropped because I would have had water all over me and the loom.
For the last couple of yards I weighted the warp over the breast beam.
After I run a few errands I'll thread and sley and see how it works. If I like it, the next time I'll use 20 oz. water bottles for the weights. The milk jugs, no matter how well I washed them, were a little funky smelling. Just another reason I'm glad I noticed before the lids got knocked off!
For short warps, or when designing in the reed, I still like the F2B method I learned from Tom Knisely at The Mannings. He has an instructional video that is the front to back method part of the chain warping class I took a few years ago.
