I haven't actually used this for anything yet. I did however disassemble and check everything. Initial run-out was 7-10 thousandths and I was disappointed. I then installed the dead center and checked run-out and it was .0005 in. OK. that is great! I then re-installed the chuck and chucked in some ground drill rod and now run-out is .00025 in. WOW! Backlash is adjustable and was nearly perfect. The index plates look accurate so dividing should be accurate as well. I couldn't be happier with the value and the quality far exceeds my expectations. I was surprised there is no lock on the face plate to the spindle, not having used an dividing head before, I have no idea if this is normal. so while it's is possible to drive this up to 2400 rpm (its in the manual) there is no lock to keep the chuck on the face plate so turning something in reverse could unscrew the chuck. I'm not driving it so I don't care. I've paid nearly the same price for my MT-2 JT3 Jacobs chuck (super ball bearing chuck and arbor) for my drill and it has more run-out than this table.
