hammer travel / burning angle

[Ric Brekne]

Hi Julia

Burning angle refers to the process of heating shanks up so as to be 
able to twist the shank so the hammer lines up better on its intended 
path at rest. This is usually the last step involved in installing new 
hammers.  If the shanks are traveled well enough to begin with, and the 
hammers are glued on well then you shouldnt need to do much of this.  
The less the better actually. Shanks can get a bit rubbery if heated to 
often or too much.

Cheers

       What is meant by the burning angle for hammers. The bore angle? 
Maybe
I know this concept by a different name.
