Yup, I HAD one of those. The X and Y slides are so flimsy, you can
barely mill
anything at all on it. I was very disappointed in mine. The rotary
section itself
was pretty good, and there was not much backlash. I did mill some
things while
rotating on it, and didn't have much trouble with things jumping
around. The rotary locks
were pretty poor, though. Oh, I think mine was a 6" Palmgren, so maybe
the 8"
is a bit sturdier.
