[TheForge] Draining the lines

[Bruce Freeman]

I seriously doubt anyone would need 3/8" tubing to feed a forge.

It depends upon the pressure from the tank and the flow needed by the
burner.  If you can pull the propane off at full tank pressure and put
your regulator at the end near the forge, then I'd bet on 1/8"
sufficing.  There are ways of calculating such things, but that's not
my line.
