Re: Drying down a panelAddendum:

You'll need about 3 1/2 sheets of whatever stuff you build the box out =
of.

You'll need three or four 8' lengths of fair to good 2 x 4s. Rip these =
down the middle and use them to buttress the joints and for spacer =
blocks inside the box.

The oil-filled heater I mention should be of the baseboard variety. It's =
better if you use a separate thermostat located some distance away from =
the heater itself.

You'll want to put this thing up against the wall and fasten it to the =
wall for stability.

You can also use it to dry out the occasional action.

    Thanks Ron, but I'm not as young as you think.

  In that case, and depending on the volume of work you intend to do, =
you can build a simple box large enough to accommodate the largest =
soundboard you expect to be working on. Something on the order of 8' x =
5' x 1' should do the trick. Use flakeboard or something similarly =
cheap. It's easiest to use the ends as doors but much more convenient in =
use to make the doors on the front. (Put a 1' strip across the bottom =
and split a 4' x 8' panel into two 4' x 4' pieces. Use "piano hinges" at =
each end. Don't worry about making it completely airtight -- you'll want =
a bit of air exchange going on. Put in a couple of posts and braces to =
keep the soundboard panel(s) up off the floor and spaced away from the =
walls. Down in the lower right hand corner put a small oil-filled =
electric heater. This should be a fairly high quality device with a =
decent thermostat and a low-wattage setting (300 to 600 watts will be =
adequate). Above (or beside) this place a small, non-oscillating =
electric fan to keep the air blowing gently around.

  Go back to the archives and find Ron's description of his handy wood =
moisture content meter and make one. Set it up somewhere toward the =
middle or top.=20

  Put the panel -- more or less centered -- in the box. If you're drying =
more than one panel use wood stickers to keep them separated. Turn on =
the heater and the fan. Check the wood moisture content meter daily. =
Once you have everything down to the MC you want, turn down the heat and =
leave it all to stabilize for a few days.
