** I build a cardboard box mock-up enclosure, duct-tape stuff in place,
measure the delivered pressure with a manometer, and, if needed, I make
changes. I have found few blowers blower that meet the mfg's claimed
specs. // The rule of thumb for blower selection: If the tube blows
out of the socket when one's thumb is removed from the anode, a smaller
blower is probably a good idea.
