Dennis,
Instead of particle board, I've had good luck using MDF,(Medium Density
Fiberboard),from your local DIY warehouse. It's very strong, easy to work
with, and it doesn't crumble like particle board. It comes made into
shelves,(already primed),  and 4' x 8' sheets. It has a very smooth surface,
so it comes out nice when it's sealed and painted.

Keep on Coilin'

Sparky

	Others have gotten good results with the primary
	conductor directly in contact with wood or particle
	board, but I'm not comfortable with the idea.  Wood
	products are OK for a primary deck foundation, but not
	for insulation.  Use plastic, glass, or ceramic stand
	offs of some sort so the copper tube isn't in contact
	with wood.  I used PVC pipe insulators.  It was cheap
	and effective.  Have a look at the world's simplest,
	cheapest spiral primaries at:

	Cheers,
