Found the perfect seperator drum today on craigslist. It's a 55 gallon steel drum with a gasketed plastic lid and a clamping ring, for $15 bucks.
So I made the baffle, cut the intake into the side, and fired it up. All I can say is WOW, I can't believe how well it works, everything stays in the drum. I even load tested it by dropping the end of my DC hose into a big bag of planer shavings, and nothing went through to the DC bag. I wish I would have found this site sooner.
NICE! Another side entry :D Gotta love it. I have that same DC too! Good job.
