@Cyborg , its a lathe.
And the set is statically balanced.

The lathe stays on its foot, as does the whole neighbourhood.

See the little boring tool with cbn tip in it.

I noticed the balancing holes. You do very nice work!
This is why I can’t spin things at 3,000 rpm.

I was turning some cast aluminum a while back and these deadly looking things started appearing. Maybe I could get a job making razor wire for the local penitentiary?

You put the shoe on the jig. As in these pictures. Pivot the shoe and when the spring is adjusted correctly the hole on the shoe should line up with the small hole in the jig and the C11/1 pin thing should not compress the springs any more. Not a very good description. As the shoes are not symmetrical the C7 uses the other side of the jig. Somewhere someone gave the dimensions for this jig. Eugene had one made and I copied his before he scuttled off to New Zealand.View attachment 45805View attachment 45806
Roy Cross was the person who posted the plans for this jig in an old mph.

Many, many plans and jigs in our old mph’s. Maybe not in the future.

Thanks Ed , I made mine out of Wood,
I found it does not have to be spot on,
But it's a good Base Setting.
Cheers Bill.

I meant to mention before Bill. You'll get a great benefit if you can weld in squish bands before you machine your head. That's what those pistons are designed for.

Cheers Bill
