Re: hexapods for machining

Elliot,

I saw a hexapod prototype in LA a few years ago. They had a high
speed spindle, maybe 5 hp, demo'ing various cuts from different
approach angles on something like an aluminum aircraft rib
structure. Seems like that unit was about 12 to 15 feet high.

I agree, stiffness would be a problem. Hogging steel with a 40 or 50
taper doesn't appear likely.
