driving tuning pins on a samick grand

[John Ross]

Speaking of jacks.
I went to a car wrecker, and got two scissor jacks.
I used them when working on grands, removing legs etc.
I use one of them and a piece of pinblock material, to support the bottom of 
the pinblock. I use that instead of the machinists jack that was sold by the 
supply houses to do this job.
It has a larger footprint, so doesn't need the pinblock material, below to 
distribute the force.
