[CAUT] hammer burning experiment

[Wimblees at aol.com]

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?
