[pianotech] tightening balance hole was Bouncing Bostons

[David Skolnik]

Oh Al, It's just the old  fire extinguisher body, with a big bolt 
closing the hole where the gauge used to be.  Brazed into a 2" hole 
in the bottom is the flange for a hot water heater element.  Along 
the top is a row of drilled out zerk fittings, which act as 
nozzles.  It all sits in a plywood cradle that the keys can be 
balanced over the holes. trick.  Actually, a video would also be 
interesting.   So, Ed - no glue-size, eh?
