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.

Lookin' good! I hope that lathe won't be staying that clean.
 
Good work, don't leave the chuck key in. :grin:

Nope, I’m my hand or in my apron pocket

That’s after cleaning up the cast iron mess. Did I mention that I don’t like that stuff?

Doing a bunch of cast iron parts for a steam engine. Washed my hands in the kitchen sink one day and the iron dust stained the plates sitting in the sink with rust. Can’t get it off.
:rolleyes:
 
Yikes!
As my first foray into making chips they covered my hands in black oily mess.
