Tim,

As for a web site, check out:

and inparticular:

If you check out my article on media plasting:
http://www.team.net/www/morgan/tech/blasting/mediablast.html

You'll want your dryer away from the compressor output a ways.  Otherwise the
air is moving so quickly at the output connection there is NO time (chance) for
any of the moisture to be condenced out of the air.  So I made  a 
copper cooling
coil (which is what is in the bucket) by coiling the copper tubing around a 2 L
coke bottle.  I can fill the bucket with water (and even add a frozen 
water filled
2L plastic coke bottle) to help cool the air coming out of the 
compressor.  Then
you my dryer is attached to the left hand back 2x4 of my work bench.

Hope this helps.
