End Delivery Shuttle tension issue
I've been vexed with this issue and hope someone out there has the knowledge.
I use end delivery shuttles. I have several, fly and hand throwing, all sizes, and through use, have designated many for certain threads, because i know they work well on the both selvedges. Currently, I'm using a small hand shuttle with tension on front and back near the nose.
My question is this:
If the left selvedge is tensioned correctly but the right selvedge is loose, what's the trick to tensioning the right, without messing up or tightening the left?
Does the front tension hole affect one or the other? There must be rhyme or reason to the two and how they affect each edge. I experiment past the point of no return.
I just wove one piece with a certain yarn, and didn't have to tension either side, finished that, and on the same warp, began the 2nd piece, new color, same fiber, and floppy right edge! aghhh.
Thanks for any insight.
