Hello list,

I once came across a grand that had new hammers recently installed that =
had not had any tail-shaping whatsoever. I used a dremel tool with a =
sanding wheel to shape them, then regulated backchecks. It would have =
been better, of course, (if the customer had been able to pay for it), =
to have the action in the shop for a proper tail-shaping and regulation, =
but that was my in-the-field, on-the-fly solution.

  John, thanks,  I've seen this too and I might have considered it if =
the tail
  were straight.  They are tapered the wrong way, so the backcheck would =
be
  twisted severely.  This might put side stress on the hammer flange =
resulting
  in premature loose center pins.  I'm putting my ingenuity and =
foresight  to
  work on this dilemma and I'll let the list know when I bring forth my
  ultimate breakthrough creative solution.
