As everyone else has stated, tear it down,file off burrs and grease well,I have milled a bit of 1/4 plate with this and it holds up well, I have a pretty beefy ITC press with good size bearings so a good steady lateral force is no problem, if your planning to attach this to a smaller press to do any milling, be careful because the Jacobs chuck is is just a tapered fit and it will fall out while your operating it.?It is pretty true and sturdy.minimal tightening on gibs will reduce unwanted XY movement .Lot_ of backlash on allthread drives, if you_e prepared for it , it_ not a problemI would purchase again
