[CAUT] hammer burning experiment

[Don Mannino]

Wim,
 
I use one of those long barbeque lighters, and wave it back and forth
the length of the shank.  It spreads out the twisting action over a
longer area.

Subject: [CAUT] hammer burning experiment



Someone asked if I could do an experiment of my burning technique to see
if the hammer was moving or the shank. I've got a box full of old
Steinway S hammers glued to shanks, (They are not genuine Steinway
parts), on which I did the experiment. I scribed a line across the shank
and the hammer, and using my Weller heat gun, heated the hammer, and
bent it off center, the way I normally burn a hammer. Guess what. The
hammer did not move. The shank turned. So all this time I thought I was
loosening the glue joint, when I was in fact, I bening the wood.
 
As I said, I heat the shank at the hammer. The question I have is, where
do you guys heat the shank? How far from the hammer?
