RDH- dropped a line saying:

One interesting, um, aspect of the regulator I earlier posted about (from
the Surplus Center, for $7.99) is that it seems to be thermally-sensitive.
It seems to drop regulated pressure by 1/8 - 1/4 PSI per 10F; left lying
in the summer sun I lose a coupla psi to run at 12-13 PSI


	This is something that ned warned me about.  I can think of
	several reasons.  The unit operates with a spring and with
	an elastomeric washer.  Either could have properties change
	~f(temp). I should check this out on the bench first!

	p.s. RDH, I can't return email directly.  Would need IP number.
