I have an assembly I need to ride on two linear motion rails, so two sleeve bearings per rail. I have the assembly tapped for the bearing blocks, but if I tighten all blocks the bearings bind. If I let one of the blocks on the rail "float" by loosely attaching it with only one screw then the rails move smoothly (see photo below). How can I secure all the blocks without binding?
I'm assuming I have to shim the floating blocks, and then I'll be able to screw them tight. But I've never tried this before. What tools, materials, and tricks can I use to accomplish this?
