  The jack tender is in two pieces so the grain orientation is correct =
for strength. Imagine if key sticks were cut out across the grain; they =
would soon snap in two or even three pieces.

    Ran into my first loose jack tender today, on a 1969 S&S M.  The =
note blocked on my first run-through, and adjusting letoff didn't help.  =
Sure enough, the tender pulled right out of its little mortise and tenon =
joint (along with two others in the high treble that weren't blocking =
yet). =20

    I CA'd them (protecting the action center with pieces of business =
cards, as per the PTG's Field Guide), but it made me wonder: why are =
those jacks made in two pieces to begin with?  Is it just so they can =
fail in a repairable way if regulation is off (too much aftertouch)?
