For cheap entertainment, here are some pics of my project today of modifying
the touch weight on previously mentioned Young Chang

 

I used Spurlocks jig for shaving the hammer tails. It was really designed
for using without the shank glued on, so I had to be very careful. I took
about 1 g out of the hammers in bass, about half gram from treble.

 

 



 

 

 

I used the drill press for pushing out the lead weights. I chucked a short
1/4 drive extension and put a deep well socket below. I removed 2 weights
(out of 5) from bass keys, one from tenor up. 

 

 

 



 

 

Ended up with about 5 lbs of lead
