[pianotech] hour$ pinning

[Don Mannino]

Ed,

My record, when actively repinning a LOT of actions at a certain 
manufacturer in the early 90s, was 50 minutes.  This includes removing the 
parts, repinning, and replacing the parts.   I had the help of a power 
screwdriver and the pressure to finish before going out to lunch.  I think I 
also put off going to the bathroom until I finished to give me extra 
motivation.  :-)

I think your 90 minutes is a more reasonable good time to do the job, 
though.  I used to estimate that part of an action job for 2 hours, to allow 
for problems.
