Before reading you last post I had just got done reading about scraping. I think this is what I need to do, I can feel the bearings getting tighter as I tighten the aluminum plate. I used a feeler gauge last night and there is about .005 difference on one of the four corners of the bearing truck. I tried inserting a shim and it didn't work (as I had thought). At one end of the rail the truck rolled free and at the other end it was in a bind. I think I will have to get some blueing dye and start scraping/sanding and see what I can come up. Did you say that you have a lathe? Would you be interesting in machining a bearing surface on a ball screw? |
