There is that as I too have an out limit about 20mm inward from the OEM lash up. Moving the tool holder to the right and 1/2" outward would both be desireable moves. Might need to use the old setup long enough to put a taper for chuck jaw clearance though. :) But at that diameter, best done on the mill as the drive parts at that diameter would be falling out in pieces as the 1 HP motor breaks them. BTDT, way too many times already. Thanks Andy. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
