I just bought a bunch of chinese ballscrews/nuts from Linearmotion and I am going to need to turn one of the ballnuts down to mount bearings on it. The body of the ballnut is apparently 28mm (I haven't received them yet) and I'm going to need to turn it down to 25mm. is there 1.5mm worth of meat that can be removed from the ballnut body? If not, I'm going to need to formulate a new plan.
