Right! It really is a matter of acceleration, not actual speed. And,
if you
don't have your Brigdeport anchored with 1/2" bolts in a foot of concrete,
enough acceleration to make a real difference in a 1" move will tip the
machine over on it's side! The acceleration required to get up to 120 IPM,
travel, say 3/4"and then stop again is considerable!
