Depthing tool plans

The holders with acorn nuts were tightened firmly with regular nuts and locked with acorn nuts; these hold the hinge rod firmly anchored to that plate. The knurled knobs on the hinge rod allow loosening to adjust gear mesh, then they are tightened to lock the plates at the desired angle. The plates were drilled and countersunk as needed to clear the rod holders.

The rods which hold the gears have a cone shaped depression in the end to accept the end of a gear shaft. The cone was made with a countersink; my center drill left a small bump in the center of the depression so it was not suitable.

I measured the distance between the rods on one end and compared it to the distance between the rods on the other end to judge parallelism; the difference was 0. Apparently, lines parallel to the same line are almost parallel to each other when I build things Weight and balance is perfect for upright or reclined position on the bench.

This tool can even depth mainspring barrels. As an add-on attachment. Site created and maintained by Mike Korn , Centennial Colorado.

Generally clock wheels are not very thick, and a short tool would be less prone to torsion. Joined Nov 17, Messages Have you checked youtube? I recently seen video making whole tool. Check out clickspring. Joined Jan 29, Messages The hinge appears to be a ground and polished rod sitting in a groove.

The rods holding the gears are also sitting in grooves. Parallelism is maintained by cutting the hinge and gear holding grooves in parallel in a single setup. A spring is used to hold the plates in contact with the hinge pin.

It looks like an elegantly simple tool. So long as the rods are straight and the grooves parallel everything should work.

I have a project in the queue that uses gears and plan on making a pinion head depthing tool similar to the third picture. This link is to the first of a three part Clickspring Video showing how to build one. Jcl Registered Registered. Joined Mar 16, Messages 9. Depthing tool images Cranerd, the sixth Depthing tool from the top of your page of illustrations is my depthing tool.

At some point I must have posted a picture of it on the internet. I did not make it. It was made by the now very late Ernest Taylor, a watch and clock maker in Waltham, Mass. I think he made it around , or earlier. He was a close friend of W. Nichols, who founded the Nichols Machine Co. They worked together on a number of projects, and I suspect that Mr.

Nichols helped Ernest make the depthing tool.
