All that is involved in adding heddles is removing the anchor pins in the jacks, one at a time, dropping the cords down through, removing and/or adding heddles to the shaft, then threading the cord back up through the holes in the jacks. A bobby-pin works great for threading the cord back up through the holes in the jacks, then put the anchor pins back in, making sure the shafts are level. (Note, this is for the older style Glimakra single unit drawloom, from 1984 or so.)
There is one shaft and accompanying jacks not on the loom. I am sure the shaft bars are upstairs, but I’m not sure about the jacks, so I will check for them tomorrow. Once they are on the loom I’ll be able to add the last 200 long-eye heddles.
Right now, I am making sure the heddles are not twisted, then adding the lower shaft bars back in. This is not a difficult task, just a bit time-consuming. I would rather do it properly now rather than encounter difficulties when threading or nearly ready to weave.
When the lower shaft bars are all in and twisted heddles are straightened out, I will add a long string to each lower shaft bar which will keep the bottom half of the heddles from slipping off the lower heddle bars. Pic(s) on that will be posted in a day or two.
The plaid towel is off the loom and upstairs along with another towel, next to my sewing machine. After the hems are sewn, a photo will be posted here. Right now, back to the heddles.
