    I'm guessing he'd get a second VFD so he can have independent controls for each machine. You can get a decent VFD for the mill for $100 on amazon (Lapond has good support and manuals). Your proposed...

    Concur with John, the best you will get new for $1500 to 2K is a benchtop Chinese mill. Those scaled down BPs are around $4k. The OPs mill will easily get 1500-2K in New England. Those 3/4 scale BP...

    I heard just recently some evidence that limiting spindles at say 90% of full speed added to their life significantly. But if the 12k and 15k are the same mechanically you are already doing that, and...

    You won't find many drills significantly larger that 3/4" in MT2 because the taper will not drive them without spinning. I have seen up to 1" though. General rule is not to drive something much...

    Agreed. Rusty and non-powered to me is about worth little more than scrap value. He's just dreaming waiting for a buyer without a clue.

    1) Off all the badness that could happen I do not think a crash would warp the saddle.

    2) Yes the saddle should sit down under its own weight and no you should not use the rear gib to pull it...
