1. go to Sears and spend $5 on a set of feeler gauges.

2. in my experience with parallel-tube quench gaps, more air is always
better.  Note that when you are attempting to force air through such a
tight constriction, you need a fan that has a high back-pressure
capability, such as vacuum-cleaner motors, "regenerative blowers" and so
forth.  Regen blowers can be found in some old mainframe computer tape
drives, among other machinery- check your local surplus stores.

It is unlikely that you are actually getting 108 CFM out of your fan,
becuase that rating is at 0" of water pressure.  Grainger and the like
sell large regen blowers, but they start at $340.

PS: while we're on the topic, if anyone has, or knows where I can obtain
cheaply, a very high pressure & high volume axial-flow turbine or regen
blower, please let me know.  I'm looking for something appropriate to a
cathedral-size pipe organ. If you're familiar with SRL, think of
something about the size of the one Mark uses on the stationary
pulsejet.
