So the 4-jaw is completed.
First let me say that I hate cast iron. What a mess.
I took my time and eased up into the register diameter. Fits like a piston.
Total runout is about 3 thou. Being that it's a 4-jaw that's good for my needs.
One thing I'm not happy about is that that when turning it to final diameter I broke through the counterbores for the mounting bolts.
Shars sells the cuck and backing pate as a pair so I would have expected that the bores would be sized so this wouldn't happen.
I will let Shars know about this as I think it's an issue. I'm not unhappy but I'm not thrilled either.
If I had it to do all over again I'd have bought one of the 4-jaws from HH Roberts.
On the plus side, this was my first attempt at any actual machining and I'm pleased with the result.
