Wim, doesn't it wick up into the felt a bunch?  I've never done the regluing thing. I've always just replaced with a spare hammer I have, or talk the customer into a new set of hammers (rare for uprights good for grand customers).  I'm thankful that if it happens at UNL, I just immediately order a new set.  Hasn't happened once since I got here in 2006. Maybe Richard West saw this, but I would have found out about it by now. Would Gorilla glue work? Too much mass added to the hammer?  The others will probably follow on this particular set. My 2cents.

It sets up in about a minute.   Wim   -----Original Message----- From: CHARLES BECKER <cbeckercpt@verizon.net> To: PTG <pianotech@ptg.org> Sent: Sat, Feb 4, 2012 4:59 am Subject: [pianotech] re-gluing loose hammer felt Hello list,   What is the best glue to use when regluing loose hammer felt to the moulding?   Thanks in advance.   Chuck Becker
