Here are a couple of mods I made to my Tandy stitching pony.

Thanks for the tips and ideas. I though I was the only one who had problems with the thread catching on the wing nut. :)

I made a "spoked nut" that fits between the clamp jaws that you rotate to open / close the jaws; nothing to catch on, at least on the outside.

The spoked nut is made from 1-1/2 inch diameter aluminum (6061) stock and is 2-1/2 inches long ( the distance between the jaws). The center diameter is 1 inch long by 1-1/2 inches in diameter, and the outer lengths have been turned down to 1 inch diameter (mainly for appearance), and are ¾ inch long each. One end is drilled and tapped 3/8-16 x 5/8 deep for the shoulder screw and the other end is drilled through to the other hole and tapped 5/16-18 for the carriage bolt.

The shoulder screw is ½ x ½ with a head thickness of ¼ inch. This goes into the fixed jaw, which is drilled through with a ½ inch diameter hole and then counter-bored ¼ inch deep x ¾ inch diameter to accommodate the head of the shoulder screw. When installed in the jaw, the shoulder screw is tightened hard against the spoked nut and should turn freely with the nut, as the nut is turned. If it doesn’t turn freely, make the counter-bore a little deeper.

The moveable jaw is drilled through with a 5/16 inch hole for the carriage bolt and counter-bored to accept the head so that it is flush, or slightly below, the surface. The carriage bolt is 1-3/4 inches long.

The spokes are 2 inches long x ¼ inch diameter steel dowel pins and are pressed into the center hub of the spoked nut, 120 degrees apart.

When assembling, screw the carriage bolt side all the way in first, and then install the shoulder screw.

That’s about it; pretty straight forward.
