[CAUT] hammer thickness trimming jig

[Fenton Murray]

[CAUT] hammer thickness trimming jigI've thinned several sets of hung hammers on a sander. I use the disk and the small belt free hand with the hammer supported by a table. I make a couple of go/no go gauges to keep me honest with the tail and the head. It's very quick and easy if not perfectly accurate beautiful machining, but it gets the job (weight reduction)  done.

  Table 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.
