    Some of those driveshafts are hardened steel.  Was it difficult to drill?

    I spot drilled them with a machinist “center drill” on the milling machine,
    the switched to the size drill bit I wanted. I managed to drill the first
    hole to depth, about .200, but the drill wouldn’t touch the other
    hole, nor the other four bits I tried, lol.
    I ended up using the center drill to go to depth, which worked okay,
    but I had to use a larger diameter pin than I intended, which
    may have been better anyway.

    Prepare to be boarded!
