Turned Twill on Jack Loom
I was so excited to do my first 8 shaft pattern on my Nilus II Jack loom. Getting the warp on the loom, threading sleying and tieing on all went well. Then I started weaving, and I thought things were going well. I was getting the pattern. But when I looked closer I was getting a lot of floats. When I investigated it seemed it was always the thread on shaft 8 when I was using treadle 1. That treadle lifts up 1 , 5 , 6, and 7. But the thread on shaft 8 doesn’t want to fall down. My tension is quite tight. I’ve been changing the shed when the reed is at the fell line. But now I’ve resorted to checking each time I press treadle 1 to make sure the threads which are supposed be down have indeed fallen. It makes weaving fairly slow, but I’m loving the pattern. Just wondering if there is anything else I can try. I’m weaving with 8/2 cotton at a sett of 20

You can try attaching a spring/bungee cord about the length of the distance between the shaft at rest and the treadle. This will tend to help hold the errant shaft from rising when it is not supposed to do so. On the 3 up shed, the tendency is for the 4th shaft to want to rise with the rest, so you may want to get springs/cords for all of the treadles if doing #8 helps.

Thanks Laura – I’ll look into that. I think that’s part of the problem, but I feel that the biggest issue is just that the bottom thread is loose, and it catches on the raised thread, seems more a stickiness of the threads in the same dent. There are only 2 in a 10 dent reed.

If the sticky threads are only on Shaft 8 and you’ve got a treadle to spare, you could tie one treadle to only S8 and then step on it before the offending sheds. That would separate the threads on S8 from the rest of the herd before opening the shed, and might reduce the stick factor.
