Hello!
I'm having an odd problem tensioning my warp. I'm working with 8/2 cotton, and the warp is 20" across. The loom is a schacht baby wolf.
I warped the loom from front to back. When I tied the warp to the front apron rod it initially seemed like it had completely even tension. I then fine tuned this by weaving a couple inches of tabby before beginning my pattern. Soon after beginning to advance the warp the tension began to change, becoming loosest on the left side and tightest on the right. The change in tension was not so large - it didn't seem to have an adverse effect on the structure of my weave, at least not to the naked eye. I know that it is not perfect though! I wove on it for about a yard, and then convinced that it was causing troubles decided to stop and finish a practice piece. The practice piece turned out fine after a hot water finish.
I again tied on to the front apron rod, this time adjusting the tension in a slightly different way (I always begin in the middle and work outwards and then revisit to tie the second knot, but this second time I did so without feeling the tension of the warp very much for fear that touching it might have created the original inequality). Again, it started out fine, but as I began to advance the warp the tension began to change. It almost seemed as if the apron rod was bending on the left side? It is just so strange because the tension seems to change in an almost uniform way, getting progressively looser as it goes towards the left. This time, since it hadn't seemed to have any ill effect on my sample, I decided to leave it and weave and see what happened. About a yard and a half in I began to see some bumps in my weft. . .
I'm so confused and can't seem to find this problem addressed anywhere. Help?
Thanks!
