Loom breakdown
Warp line
This needs to be under tension all the time. Otherwise the work won?t look its best, that is, even throughout. Tension is achieved with the weight and pulley system. The pulleys enable the warp line to be of arbitrary length (very long). So miscalculated and too short lengths are of no concern.
Line brake
The brake separates the spool of warp line from the tension of the work. It prevents the spool to be dug into and deformed by the tension at the work side.
In my loom, it is fastened at the lower end, and is able to move a bit. At the top, the turns of the line are kept by a wooden peg.
Tension weight
Adjust the weight to suit the desired work or warp line. As the line is wound to the object in progress, the weight will gain altitude. So you need to scratch or stroke the brake to unsettle the warp line. Take care not to allow the weight to touch the ground. If that happens, tension is lost.
Vise grip
A carefully adjusted vise grip will let you fix the grafting without damage. And thus take a much needed break.
Hooks
So far, my graftings have been sturdy. That means the warp line is tight enough to pull the work upwards, vise grip and all. In pause mode, work and vise grip is rested in the downwards pointing hooks. When resuming, pull the work down and out to continue.
