I have a counterbalance floor loom. It's my pride and joy. (Counterbalance looms are like hen's teeth in Australia.) I've finished one project on it and am well under way warping the next, so I'm still in the honeymoon phase. However, this honeymoon hasn't been without its issues.
The Problem
Like a lot of pulley-based looms, mine has wooden shafts top and bottom that float freely in the castle - no sides or guide rails. This can make it difficult to thread the heddles. They wave around and bump into each other, and before you know it you've threaded shaft three with shaft four's intended thread, or worse - threaded *both* together.
