    As some others have said, just making sure you get complete coverage of the bond area, with a surplus of cement, along with priming on a clean surface, should be about the best you can do.

    When I need to work to a half-thou on MY Bridgeport, I just cover up the Bridgeport name with a magnetic Moore nameplate. It is simply a mental adjustment to make one's knee mill into a jig...

    I ran into this issue previously after I lost my patience with an "inexpensive" Chinese 5C collet indexer, and decided to make a new drawtube for it. I measured a number of 5C collets with wires, and...

    Wow -- that must be some fancy mill you have with a flat table and a close-fitting, cylindrical quill. We should ALL be so lucky;-)
    Great idea, though, using the granite right angle. You're...
