Thanks Ballendo. You got me thinking with that. I was actually hoping to
adapt my Albrecht chuck (with a ?JT-1MT arbor), and I think I can chuck the
Albrecht up in the 4-jaw, indicate it, and turn a piece of .375" on the
arbor to hold in the endmill holder. I can turn down the existing 1MT on
the boring head too (since 1MT is comfortably larger than .375 diameter).

I was hoping to be able to do something that didn't project so far from the
spindle nose (like cutting 3/4-16 threads in the back of the boring head
and Albrecht) but the boring head is slotted almost to the back, and the
Albrecht body is hardened and ground already, and might not have enough
"meat" anyway...

Your solution is simple and practical.

Best regards,

Randy
