When moving the part in and out and trying to hit against a shoulder, one does not need to be fighting a ton of backlash. Our current B&S has been causing problems in making tooling as the table moves in and out uncontrolled while feeding from left to right. Gibs are set tight but to no avail. We took a look at the leadscrew and the center section is so worn that the thread is now more like a standard 60 degree instead of acme. Near 0.050”! The brass nut has nothing left to give as the adjustment will not allow smooth action from end to end of the leadscrew. We have been searching for a less worn or NOS but there is nothing out there. We have looked at replacing with a ball screw which would work as the lead screw is protected fairly well from the grinding dust. It is just more economical to find a newer or new machine.
The magnetic chuck has to be ground flat if it has been removed and put back, otherwise it may not hold size across the whole surface.
