I recently bought a custom made 4 shaft counterbalance loom that was made in 1960. It has been unused and stored in a garage for the last 15 years. I have refinished the wood, disassembled the shafts so I could clean the heddles and the bars. They cleaned up well and I have reassembled them. The loom uses the pulley system and the metal pulleys and rope need replacing. I was wondering if it would be better to replace the metal pulleys with a roller bar system. Another thing is that on either side of the shafts, there are long vertical pieces of wood that have channels for the shafts to move up and down in. I would appreciate any advice on this matter. I started using the Rigid Heddle loom 2 years ago and so this is new to me. Thank you!
