Yooper - good call on heating it up - I should pick up a wine whip next time I'm at the LHBS (local home brew store for those readers unfamiliar with beer terminology).
A wine whip is better for mixing than degassing, hook your foodsaver to it and let it suck away. I throttle mine by eye and let it hum away. I actually don't have a vac gauge so I don't know how many inches of mercury I'm actually pulling. Never blew one up yet....I think the stopper would get sucked in first.
a 3/8" barb fitting fits a drilled bung nice and tight, get a slightly larger bung, a 3/8" barb to NPT, then NPT reducer and barb to whatever size your foodsaver hose is. Polyethylene tubing is cheap and works perfect.
