Watching for interest, ................. how ever aren't most seat slightly hard(ened) ?? However given what material you have on hand I would say leaded steal....

The cnc version of the screw machine......wow there's a lot going on with machine

Interesting idea, I'm gonna have to think about that

That's funny....uuhhh, no. For certain parts , a screw machine will run circles around a CNC......

Ahhhh the uninitiated.....that is a (brown and sharpe double zero) screw machine

On my PMR number 3 I did get the steam inlet done, I opted to tap ¼-28 , because the tap called out is $60 .....ouch......once again the fixture makes all the difference......easy to find center and with a section of drill rod easy to find the center of the bore........after figuring out a 5...
