Role of the Staple on a hammer

[David Love]

Yes, that is what I was trying to say.

David:

Would not another reason to keep the staple be that the underside surface of
felt that is glued will most likely remain glued (barring abuse), and the
thicknesses of felt above that surface will stretch toward the strike as the
felt is compressed around the wood core, as well as slippage over time after
compression? Or is that what you are saying when you use the phrase, "...the
staple does play a role in maintaining the overall tension in the felt..."?

Other than nominal hammer weight control, I have never felt compelled to
remove the staple, and I have never quite bought the idea that it was there
to keep the glue joint from failing.

Subject: Role of the Staple on a hammer

An older subject but I've been meaning to comment on this.  A few things






have been written about whether the staple is necessary to secure the glue






joint on a hammer.  While I do agree that the glue does most (if not all) of






the work holding the felt to the molding, I think the staple does play a






role in maintaining the overall tension in the felt.  Hammers without






staples must resort to reinforcers (which I have done on occasion) or some






application of heat to stabilize this region.  I think the use of heat to






create stability has a potential downside in that too much will simply






remove tension from the felt rather than reinforce this area in any






particular way.  For that reason, I'm not yet ready to abandon the use of






the staple.
