Bought a 1" plug at a local auto parts store. $3. Other sizes available, but none smaller.
I should find out at the end of today wether or not I'll win the controller I've been eying.
This week; keeping on the flow calcs, and paying Bill a visit.
Sidenote: went through the
Leybold vacuum primer (200 page, is there anything better to do on a Saturday night?

), for the heat die / test chamber. Most informative! Spent Sunday repairing my bumper.
