[TheForge] GAS FORGE QUESTION

[Gladish Family]

I'm using one of Grant Sarver's excellent squirrel cages (actually I don't
know what a PP blower is), but it's about four times the blower I need so
the air gate stays closed almost all the time, which might indicate that the
air velocity is low...
It's a real hot rod as is, this being the only issue to catch my notice. If
I turn up the air (and gas to balance) everything goes white and steel
starts burning.
Thanks for your suggestions!
