My loom did not come with all the cams available, but only the basic ones. The basics are four No. 1-2 combinations, two No. 8-9 combinations, one No. 7 and one No. 10.
Shown at the left are two of the four cams for plain weave. They are numbered I and II and are reversible. The left one is I and the right one is flipped over to be II. Four are needed to weave a simple over and under plain weave.
These cams are also used in other weaves besides the plain weave.
The above instructions are used if there is already a warp on the loom. If the loom is empty, it is easier to install the cams because the shafts can be lifted out of the loom to get them out of the way. It's a good time to add some oil to them everywhere the metal rubs on another metal part. Do the same for the cams.
I made cards with instructions on how to install the cams for each one of the designs that are in the manual. This is the first one and the rest are below. Each card shows which cam goes on each shaft, the position of each cam when the key is in the upper left position, which shafts are up and a small drawdown graph of the design.
The stripe arrangement is the thread count for the Wanstall tartan. I didn't weave the tartan since it is for Wanstall family members.
I got four generous sized towels from the warp I was experimenting with.
With my next towel warp, I will try the other patterns.
