Questions About My New/old Lathe.

Robert,

It looked like the groove pin is holding the 0.094" pin in place. I can remove the groove pin. What does it do?
 
That's what it's all about. My better half can't understand why I want to "work" so much. It's more fun than TV by a long chalk.

I'll watch a couple of minutes of TV here and there. I have two British shows I watch each week on PBS. About 10 minutes of the 'NEWS' (???) once or twice a week is all I can take. I spend more time in the basement workshop with a smile on my face these days than ever before.
 
The purpose of at least the external portion of the tapered groove pin is to prevent pulling the index pin completely out and eventually getting lost.

If the taper pin is in fact retaining the 0.094" dia. pin, then if you can get the remains of the 0.094" dia. pin out, you could replace it. But Frank gave the groove pin size as 1/8" and they do not have much taper. The slightly larger 10-42A used in the 10" and 12" is one machined piece plus a 1/8" dia. roll pin.
