[pianotech] new Faulk lever--compare with Fujan?

[Paul Chick]

I switched from a Schaff head to the Fujan head and eliminated almost all of
the flex in my shop built tuning wrench. It has a 7/16" hex shaft, 11" long.

John,
Here's a former engineer's thoughts on flex:  It doesn't matter how 
stiff the shaft is, if the connection to the head is flexible.  The 
further up the shaft you go, the less important stiffness is.  Both 
Fujan and Faulk seem to have very beefy heads, and don't rely on the 
traditional pipe thread connection.  I'm thinking that if you stuck 
either of their heads on the end of a Schaff octagonal extension lever, 
you'd be surprised how stiff it would feel.
