Hard to see because of the flash but the pocket is finished.

I get three hours a day in the shop, one in the morning and to late in the afternoon. Flu is almost gone.

OK, this morning I made the gib blank from an old brass gear. The adjuster blank is also done. Needs to be drilled and tapped 6-40.

How about a size check?

Now that is ultra-small!

Nice work Bill!

It will do a special operation inside my radial engine crankcases Ed. I'm hoping to save about 20 hrs. work.

Bill, are you making a boring head or a pocket watch?

I love seeing the intricate little parts that folks such as yourself can produce at home, and fit them together into a precision assembly.

Awesome skills there.

If this works out Highpower, I'm going to make a smaller one. The diameter will be only 1 inch. This one is 1.5 inches.

So is this one just to "test the waters" or do you actually need the two different sizes for different operations?

I can only guess that you are doing a grooving/relief operation at the bottom of a bore? I'm curious about this special operation.
If it's going to save you 20 hours of work, it's got to be a doozie!
