<DIV><FONT face=Arial size=2>Exactly my procedure, Dave. My thinking is this is
an old set of hammers that was incorrectly installed, so looks are not my number
on priority as in the machining of a new set. Also, the sander gives me very
precise adjustment of weight, like .1 gram, I can't get that on the table saw.
You can get a little on the cove and hammer felt, but if you need more
than .3 or .4 it seems like a touch on the sander is the way to go.
After machining a new set, I get the spindle sander and belt sander and disc all
going at once with dust collection and ear protection, I've got the scale set
up, then with me in the middle I go through the set weighing each hammer and
touching it here or there as needed. A little bit of sanding smear on some of
the sides doesn't bother me, air and dust collection will minimize it. I do all
the initial tapering on the table saw though, works great.</FONT></DIV>

saws and routers always make me a bit nervous especially when trying to
support the object in question with hand held pressure. It seems like
one could construct a jig where the hammer is held strike point down so that
the shank doesn’t actually get in the way and you could create some kind of
holding mechanism so fingers or finger pressure to hold things in place
would not need to be used. The width of the hammer could thus be
thinned and weight removed to the point just before where the shank
engages. A belt sander could then be used to clean up the area around
the shank were it necessary. I’ll have to give it some thought when
the shop empties of pianos (which isn’t likely any time soon). It
might be easier just to remove the offending set from the shanks, thin them
on the Spurlock jig and rehang them. The customer is paying, after
all. Why put your fingers at risk to save them a few bucks.
