I've built my own closed stand router table and I'm also looking to modify my table saw's DC setup, and I was wondering if there is a formula somewhere for calculating the size of the make-up air opening I need to allow the DC to work properly.

Anybody familiar with the canister filter sold by penn state? It looks like a direct fit on a 1200 Jet and it has a wiper blade inside to clean the pleats,  but doesn't have much for specs or what its made of.

Just bought a used Jet 1200cfm DC to replace my little 650cfm jet. The 1200 comes with a cloth lower bag, my old 650 had a clear plastic bag and I kinda like the plastic better. If I switch the 1200's cloth lower bag with a plastic one, am I hurting the performance?

I built this: http://www.jpthien.com/smf/index.php?topic=196.0  last year and its been working great, until...... I recently purchased a bigger planer.  I was using a DeWalt 733 lunchbox style planer, but now I have a 15" 3hp delta with a much greater depth of cut capacity. My problem is the shavings it produces are much larger than the old DeWalt and the tend to get caught up on the baffle unless I run the planer in slow speed and allow a few seconds between boards. The DC i currently have is a 1hp Jet 650cfm model.
My question is: Will enlarging the cutout in the baffle help or am I going to have to get a larger DC? Would the addition of an air ramp or neutral vane help?

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.

I am a new member here, been looking at a lot of pics trying to get this design into my head so I can build one for myself. In a search, I came across a reference to a video I think shows more about the seperator, but I can't find a link to watch it. Can anybody help?
