Making woodworking tools doesn’t interest me as much as making furniture, but my recent encounter with Henry O. Studley’s tool chest has me eyeing the metals section of the  McMaster-Carr web site.

The tool that turned my head is small and simple, but boy do I have a crush on it.

It’s a locking thickness caliper that looks to be made of brass or brass-plated steel. Studley had it mounted in the top left section of the right shell of his chest. It was in the front layer of tools and easy to remove, so I suppose it was used frequently.

I’ve never seen a caliper such as this, and I wonder if he made it himself. There are no maker’s marks on it. If you’ve seen this tool before, let me know. (Maybe we can get it printed on the side of a milk carton. “Have you seen this tool?”)

What I really like about this caliper is that it is ideally suited for handplaning, especially thicknessing boards.
