Thanx Sas. Willie without you I might have quit. Thanx a million for the encouragement.
Without going all the way thru I am satisfied this was a good project. Anybody recognize the three ring sign?  "Billy G"

Sorry to see that you had to start again with the dovetail Bill, but it certainly didn't seep to slow you down much! Besides, it is good for beginners like me to see how easily things can go pear-shaped.
It looks like you have one very nice boring head there and a nice paperweight too. In fact, if it wasn't for the layout dye on it, I would have thought you had paid a pretty price for it.

As long as we can think and deliver the thoughts to our hands, nothing is out of reach.
OK -- I have a set-up in the lathe that cannot be broken down till it is finished. So it's back to the mill to make the dial. The dial has a 15 degree face so I bolted my 3" rotary table to a 1" thick block. I mounted this in the milling vise at 15 degrees. I made an adapter for a micro chuck and mounted this assembly to the rotary table. Chucking up a test piece it was time to test the theory. Results below. Tomorrow we will do this with 1/2" brass. I will use the same set-up to make the graduation lines with a Dental Burr. "Billy G"

Thank you sir.
I was gonna wait till tomorrow but ------- Pic#1 is the angled set-up with the brass work piece chucked up. Pic #2 is the angled face finish cut. Pic#3 Diamond Burrs, #3 from the right are the ones I will use. "Billy G"

Everything has an end. Sometimes we hate to see it come. This is one of those times for me. I have had a ball building thel Boring Head. I got to know my new mill very well.
The dial only has .005 graduations but that is all that is needed here. Hope you all enjoyed this as much as I did. It's on to something new I guess. "Billy G"
