I have a nice little 2" Valenite shell mill to adapt to my Eklind mill

Anyone have a quick and easy method?

The drive keys? Make them separately and bolt them on after the fact.
Alternately, mill them on the arbor face, bore a hole for the pilot and
hold it in separately with a setscrew.

Just a thought

I made one with a 1/2 inch shank to fit a collet on my Emco mill. The
pilot shaft was also 1/2 inch. I milled shallow slots on each side of
the pilot shaft and brazed the drive lugs in place. Works for me. I
have a R8 holder at work that has the lugs screwed to the pilot.
either way works.
