Title: Grafting loom
Post by: Wed on August 29, 2014, 01:28:27 AM
Grafting loom
This tool came about after a few failed attempts of grafting. The thing is, several things needs to be held tightly at the same time. Not only that. Thy need to be tight for prolonged periods of time as well. Thumbs, shoulders, neck, back. You name it, it will be sore sooner or later. Not only that. But when you are deeply immersed in the work, your bodily functions will remind you of the importance of number one, or the other ...
Traditional grafting can be done. Others have done it before me. I could probably come to master it too, if I wasn?t so lazy ? I mean creative.

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.
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.

Please do. I have a nack for making things beautifully overcomplicated. Vince Brennan removed a few rough (unnecessary) edges on the design. After a merge, this is what I came up with. Simplifications or anything that makes it better is most welcomed.
