  1. I've heard that the Silva tool for facing & tapping BB shells is one of the
    nicer ones to have:

    I can't really tell from this picture how you get pressure for the facing
    operation. Are there springs there that I can't see? Also, does one nut move
    the tap and the other the facing cutter (on each side)?

    Is this tool really preferable to a dedicated facing set and dedicated tap
    set?

    Thanks in advance,

    -Bruce-

    As the taps are threaded inward, they force the facing cutters into position.
    That is why there are four handles, that is two pairs of handles on each side.
    The tap is the feed for the facer.

    It might require a bit more touch than a dedicated set, but it is compact. If
    it comes in a box, good. If it comes in a cheap vinyl pouch, that won't last.
