This little project took the better part of a day to complete. It seemed reasonable to have center
drills for both MT3 and MT4 for lathe work so got to use the taper attachment that I had just
renovated. It seems crazy but all the Morse tapers have slightly different angles to them so
had to consult with Machinery's Handbook several times. Anyway, the end product was a nice
tight fit.

Also, I wanted to have at least a small assortment of cutters for my home made boring head.
It was a scavenging operation to find some carbide scraps. I have lots of carbide but most
of the pieces were way too big. With a bit of machining, grinding, and tapping, I ended up with
what I hope to be a usable assortment. I'm not sure how the triangular carbide will work as is
but I can grind on if it needed.

Included is a photo of my new toolage, MT3 MT4, and 3/8 boring head cutters.

Looks great! Now for some projects to evaluate how well they work.
