Ed,
If you have parting off tool you could use that, start in the middle and work out. It might just have enough clearance to do it.

Ed,
I thought you had bought some indexable boring bars?

DaveH

hi well this is one way that i do it just put a slot drill in the talestock and go in

Ed,
Just plunge the boring tool in near the outer dia and move the tool towards the centre. A few thou at a time.
Now what am I missing here

Probably nothing. I was just looking for advise on ways of getting the job done.

Since dallen is flaunting his tiny boring bar, I may as well jump in with a pic of one of my smallish end mills. It's a .005" diameter carbide end mill that I used to mill a .012" square pinhole in a piece of brass for an optical application. Those are .010" graduations on the scale.

Now that is what one calls tiny

DaveH

So that is what dallen needs to mill the minute hand he is missing...

In certain company, flaunting smallness is not a good thing.
