[pianotech] hot box dimensions

I understand that risk.  I originally put the DC rods on the floor
underneath cross pieces of wood so that the panel was separated from the
rods by about 6 inches or so.  Even though I had a fan running to circulate
the air the concentration of heat at the bottom of the panel opened up a
nice crack on that side.  Oops.

When I was building it I originally wanted a baseboard heater instead, but
the radiators were cheap and available, and worked well enough. Probably
better, realistically, because the all the air coming up under the panels is
the same temperature. With the baseboard heater, it would have been hotter
the farther away from the return inlet it got unless I made a distribution
tunnel for spreading it along the heater. 
This was relatively simple, and the whole thing resides behind a big cabinet
in the shop. It's next to the outside door, to reduce the likelihood of
having stuph stacked in the way when I need to use it. That mostly works...
