I was recently gifted a somewhat worse for wear Thorpe Countermarche loom, and I'm working on getting her up and running again (I've only used a rigid heddle up until now, but I'm up for a challenge!). However, in the box of bits and pieces I received with her, I found the attached - and I'm a little bit puzzled. Warping gear of some sort? I'm not quite sure what or how those wooden clamps are meant to attach to? Anyone able to enlighten me?
