(sigh).......

Well.....it turns out than my warping bar (threaded rod) was slowly bending as I was warping the small loom.  I noticed that the center warp threads were vibrating as the wind from an open window blew over the loom.  Solution: remake the side rails so I can put in a thicker rod. 

Deconstructed one side the small loom to use as a pattern for the new sides.  Left the heddle warped, and sagging  :-( .  

Its gonna be me, a small latch hook, and a large cup of coffee when I put the new side rails on to try to lay the warp on the thicker rod.  Hopefully I can do this without having to cut it all off and rewarp the entire loom again (sigh).  Back to the workshop.....
