I believe it can survive anything that VFD can throw at it. I did find that Polish made chuck is not so true when backing into a bored hole that big, 5 thou or so non-concentric. But I've not loosened the bolts to see if it has some poor mans set-true slop yet. I need to figure out a shield for the slot in the crossfeed above the ball screw, its exposed by the time the crossfeed has moved inward 2" from the outer limit. I'm putting a scott towel over it ATM, but thats far from a daily fix IMO. > Thanks everybody.
