Drawloom Issues

Loom mechanics are something I am paying attention to at the moment. The drawloom warp was tied on, pins pulled out of upper jacks, warp tension increased slightly, and...

when I depressed treadle #1, one shaft went up, one went down, six stayed neutral, all as should be happening. The first shed was okay, I took my foot off the treadle, and nothing changed, the treadle stayed down, shafts did not move, counterweights (above) are not pulling shafts back to "rest" position. It's a mystery.

So, I have spent a day or two trying to sort this out, checking the loom over from back to front, top to bottom, and still have no idea what is wrong, so back to checking every detail again.

I've written to weavers in the Complex Weavers Double Harness Study Group, posted photos in an album, and asked for ideas, suggestions, and/or experiences with this, and replies are starting to come in.

Meanwhile, in-between getting ready for weaving guild members meeting here tonight, I'll be going over the loom again, trying to discover the problem and how to fix it. I'll keep you posted.
