No wonder. You should be adding inch pounds, not foot pounds. 
Piano tuners are usually in pretty good shape between the 
navel and neck, being used to trolling monolithic objects 
around with one hand on the lever, so it's not the torque 
that's really the problem. It's the lack of control. My hybrid 
block installations produce tighter pins than most tuners 
like, until they eventually realize they don't have to fight 
the things. Even that tight, they're easy to control. The 
Chinese produced blocks we were discussing, and those 
Kimballs, aren't.

The last couple of years the Thomaston Yamaha plant was open, 
the pinning of the pianos coming out was almost as bad.
