[pianotech] Grand Hammer Removal / Replacement

[Escapement]

Thanks everyone for the great advice.  I am going to try to file the tip on
my Schaff press down so it looks more like Jurgen's (thanks for the link and
pic Jurgen; it's on my list of tools to purchase).  But I will try the
nippers through the tail method-every other this time, for my first set-I
have a decent pair of nippers that should work ok.

Again, thanks for all the help, Gary H.

A "speed" technique is to cut the hammers off without touching the shanks.
This is done by using a pair of side cutters and cutting (a splitting of
sort of the hammre wood)from the tail up toward the shank. After a few times
this is quit a rapid hammre removal method.  There is no need to chip off
the glew collar until after the entire set of hammers is removed. 
If you want to use the exsisting hammers for a guide for hanging the new set
then just cut off every other hammer, hang the new ones then snip off the
remaining and complete the remainders.  
This can technique also be used for the verts.
Would also suggest after removing the hammers to clean up the shanks and
remove any glue. 
Schaff tools 238 They call them Diagonal Music Wire Nippers aka Side cutters
Also 3207 Hamner Shank Cutters pg 67
Shank reducer # 75 can be used (with caution) for cleaning off the glue.
 
Good luck
