<DIV>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.</DIV>
<DIV> </DIV>
<DIV>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?</DIV>
