Hello David,
Two years ago, you helped me machine some new ball screw mounting brackets that were made incorrectly. I had purchased these from Heavy Metals CNC just prior to them going out of business. Thanks to you, my machine has been happily making parts for quite some time.
I am about to machine these again just to tweak a few dimensions. These brackets use 15 x 32 x 9 mm angular contact bearings. The drawings indicate a bearing pocket with a diameter of 32.2mm.
For some reason I distinctly remember an email where you mentioned that you machined the bearing pockets to be either .5 or 1 full mm oversized.
Do you recall if you machined these bearing pockets bigger than the 32.2mm indicated on the drawing? I have heard that a slightly looser fitting bearing pocket is more forgiving with respect to balls screw alignment.
