- Page 18 PO Box 1228 Coupeville, WA 98239 PH/FAX 360-678-6225 Countermarch (general) and Cranbrook (specific) Loom length The longer the loom, the less the relative difference in tension between raised/lowered warp threads and warp threads at rest. Therefore, if the warp is held at maximum tension (as is desirable, especially for rugs), the longer the distance from front to back beam, the less resistance the warp makes to forming the shed (and therefore the easier the treadling).
- Page 19 3. If heddles don’t slide easily on the shaft bars, tie a cord around the shafts at each side so that the shaft bars move slightly closer together, loosening the heddles on the shafts (this may not be necessary on the Cranbrook; I couldn’t tell how easy it is to slide the heddles).
