[CAUT] glue/hammers

[Ed Sutton]

Eugene Thorndahl (of Bjorn Industries, supplier of fine grades of hide glue) suggested to me that a small addition of glycerin to the glue would prevent shattering of glue in the hammer head, and make for easy removal with heat.
[I haven't tested this, or figured out just how much is optimal.]

  Alan,

   

  Moulding glue is great. I mainly went back to hide because of its easy removal (we replace hammers a lot), strength, ease of use (using the “new” techniques) and “foolproof” bond – once you do it right. But moulding glue works  VERY well. 

   

  But take this class! This fellow (Shepherd) has written two books. One has something like “1000 tricks…”  I don’t own that book yet. Stephen Shepherd isn’t a piano tech, but he will be teaching the class with Vince who is a world-class technician.

   

  Best,

  Jim

  Henry, 

   

  Well, I was about to tell you that I thought moulding glue was the way to go, without any equivocation.  But if Jim Busby was humbled by all he didn't know about hide glue and is going back to it, I may feel the same way after attending Vince's class in Las Vegas.  In the mean time though, we have pianos whose hammers are glued on with either hide glue or whatever Yamaha, Steinway, Baldwin and Bosendorfer have used over the past thirty years.  The hammer sets I have hung using moulding glue are the ONLY ones in our inventory that have not developed loose glue joints between hammer and shank.  Our RH swings from 10% 60% over the course of the year.  YMMV, but if loose hammerheads are an issue in your situation, I would give moulding glue a shot.

  Hello Henry,

   

  I’ve used several glues, moulding glue being the favorite for years, but since Vince Mrykalo’s hide glue class I went back to hide. Any problems I “thought” I had with hide glue are outweighed by the advantages. Stephen Shepherd and Vince will be giving a class in Las Vegas at the convention and you may be surprised at how many tricks these guys have. I was humbled by all I DIDN’T know.

  Hi List,

  Has anyone used and had success with other type glues in replacement of hammers?  I've been wondering about the new Titebond white Moulding and Trim glue as well as the yellow glues.  Seems like out of the bottle application would be an advantage especially when it is not anticipated to remove the hammer at a later date.  Ease of use vs. ease of changing out hammers periodically.?
