Assembling a Whatsit.

Assembling a tool that I made. See if you can guess it's prime directive.

All the parts:

First wood part ' two bores filled with a barrel nut made from a cable crimping kit. The center hole is NOT functional, but there is a 10-24 thread through the sides. The holes in the side of the wood piece allow a 10-24 bolt to 'swivel'.

A long screw goes through one of the barrel nuts and a nut, washer, jam nut and threaded coupling are next joined. The nut started life as an 8-32 nut which was drilled/tapped to 10-24.

The jam nut is tightened with the screw thread going about half way through the coupling.

A cap screw with 5/32 socket will be threaded into the remaining threads of the coupler.

But first insert the coupling etc. into a deep 3/8" counter bore in the largest wood piece. The counter bore does not go all the way through but is deep enough to clear the coupling. The jam nut needed to be the small enough to fit into the bore. The cap screw is jam tightened. The screw head(phillips) and the cap screw head(5/32 hex socket) allows tightening it into one piece that rotates simultaneously.

Now for what is left. The wood piece has a through hole in the center of it's long dimension. The ends are counterbored to accept a flat washer. One end has a shallow c'bore that leaves the face of the nut proud.

The other end has a deep c'bore that allows the nut/screw to be recessed.

That long all thread screws into the barrel nut at the other end and completed the 'assembly'.

Some sort of jig for holding hand plane blades, wood chisels, jointer blades, etc, at the correct angle for sharpening? Maybe on the belt sander?

Think where a small two screw(hand/jorgensen) clamp is shown in a 'video'.
