Rob,

I'm not sure I could teach anyone. It's an art that defies explanation. 17428

I'm going to have to chuck it up between centers again because the diameter is not very consistent along the length. I think I know why it happened, and the resulting chatter pattern, and will have to come up with a creative way of re-chucking it so I can cut the whole length to a consistent diameter. Chin

Why bother with the Morse taper Ed. You'll only ever use a dead centre in it. The one for my indexing head is one piece.
Free advice is worth exactly what you payed for it.

Ah, I need a method of holding the dead center. The MT-2 arbor does that for me. Or am I misunderstanding your comment? 17428

The tailstock for my indexing head has the 60 deg point machined on the end of the arbor, one solid section.

Not mine as you can tell, far to clean

OK, I understand now. That's actually how the plans show to make the center. I was concerned that it wouldn't be hardened steel but for the use it will see I doubt that would be a problem. If it gets dinged up it would be easy enough to clean it up on the lathe. Chin

Hi Ed

Doing it your way is not a bad idea as it does facilitate the use of different types of centres , half centre etc ,as sometimes when working on the very end of smaller parts the larger centre can get in the way .

Just a thought Chin

Good point Rob. Chin

Since I've gotten this far with it I may as well continue on.
