I have been putting together some sectional dividers for my loom warp roller. Currently, I have applied one coat of linseed/turpentine mixture and will apply one more later. These sections are 61-3/4" long and a tie-on dowel rod is 60" long, 3/4" diameter. The dowel rod will seat into clothesline hooks that are ?-shaped. It will be set up so that the rod will hold the loop cord from the roller until the end at which point the rod will be pulled free of the hooks to weave the last 2 yards of warp up to the heddles.
The sections are SS rod bent on a forming block to a U shape by hand and inserted into spaced holes made by a drill press so depth is consistant and straight. Holes are drilled in the beams to attach to the roller. My roller is octagon shaped so the pieces will fit to a flat surface. The U rods are spaced so that 1" of space is between the U's, within a 1/32" and seated 1/2" into the wood.

Have a good one.
