Hi Everyone,
This is the depth tool I made 30+ years ago. It was to help w/construction of a precision clock I was going to build.
The smaller one is a commercially available one for watch work and the chunks of bronze in the rear were what I started with. The bronze had been a riser that someone made for a Delta Toolmaker surface grinder I had at the time.
When I finished this tool and went to design the clock movement, I found the tool was too small so I had to make the taller arms that are installed on one side.
I made a few changes to the standard design. I.E. the opening mechanism & return springs because I didn't like the way spring & screw just scrape against the outside & inside of the arms of the old style.
A couple of more things. Long before CNC or DROs. I didn't have a rotary table yet either. I turned my dividing head upright and took light cuts for the curved sides.
Obviously a lot of hand work too.
Best wishes to ya'll.
Sincerely,
Jim
