I can't seem to figure out how to adjust my Glimakra Vertical countermarch loom so that the top shed threads are even. I can weave without even top threads because my bottom threads are even, and my shed is large enough, but I can't figure out why the top threads are not all even. Does anyone have the same problem with uneven top threads?
You can adjust the top threads of the shed if you need to, by adjusting the length of the cord connecting the lower "lifter" lamms to the treadles. The tighter you make those cords, the higher they will lift the threads.

Thank you Becky.
How do I know if I am supposed to raise threads or lower threads? I tried raising top threads using the treadle cords. I actually did that by adding an arrow peg above the short shaft for the shaft cord leading to the treadle. And it did nothing to help raise the top threads. I went up to an additional 5 texsolv holes. So then I thought that maybe I needed to lower the other threads, to match the threads I was trying to raise to. But my cords are not long enough. I am using the cords from the Vavstuga tie up kit with the knitting needles. When I was ready to thread the treadles all of my cord markings matched up for each treadle. I did not look to see if all of the cord markings matched up. I know it is probably hard to diagnose the reason why my top shed threads are typically not all even. I am sure it could me something else I am not aware of. So that is why I am asking how a weaver knows when to raise threads or lower threads when adjusting a shed? I wish a task analysis was done by a knowledgable weaver on how to fix a shed and then using the task analysis explain how to fix a shed. It would be amazing to see just how many steps there are and how integral all the steps are. One unknowing or missed step can make the task unsuccessful.
Hello Tricia,
If the shed is off by very much, I would suspect that the levelness of the lamms needs to be checked by putting the locking pins back in.
If you have a bad shed due to the treadles colliding with the lamms, your treadles are probably too high (or too close to the lamms, which is one of the most common problems, and happens when you start tightening cords too much). Your goal is to have your shed in the center of the reed, which could help advise you on whether to raise shafts or lower them. Your beater is of course adjustable, so if you have a good shed but it's not centered in the reed that will reduce the size of your shed, which can be easily fixed by adjusting the height of the beater. My guess is that your issue is a combination of the lamms being too low (saggy), and/or your treadles are too high.
Good luck, and let us know how it goes,
Becky
I’ve had a terrible time getting my beautiful dishtowel warp underway. I wove about an inch from the magic string, and realized one shed was really messy so tried adjusting cods etc. had so many issues — shafts too high, sheds opening widely but top of reed is hindering, etc. I unhooked all cords and started from top down trying to readjust. Vertical cm standard glimakra loom. Today I’m taking off the drawloom structure which (I started threading pattern pull handles) is just resting on top. I’ll scoot the heddle shafts as far to the front as possible and start re-assessing from top to bottom once again. It almost feels like I’m going in circles. I put shafts on their hangers and adjust with the locking pin in, but jacks never really hang perpendicular to floor, whether pin is in or not. The shafts feel like they are trying to push up instead of gravity letting them rest in the shaft holder grooves. Hoping it will get figured out once I take off the drawloom rig. Really want to get my assignment done. ☺️
Update: I removed my drawloom rig and lights etc and moved countermarch rig closer to beater cradle by nearly 2”. Then, a final adjustment of the vertical jack cords for heddle shaft height, a couple long lamm cord adjustments and I’m weaving!! Found a couple sleying mistakes so took out the “header” weaving and untied from edge to sleying mistakes, double checked threading all good, now almost done re-sleying. It’s a little awkward reaching to sley, so maybe take Reed out and lay it on front warp threads to allow sleying from underneath? Very close to weaving now!
best of luck Mary,
carry-on!
