Cool modification.

How does it work?

-- Whether You Think You Can or You Think You Can't, YOU ARE RIGHT!!!

I sucked up 30 gallons of cedar shavings / sanding dust with it as a test. I could not see ANY indication of any dust, even fine dust making it to the DC, it all stayed in the separator. It actually appears to work better than my 20 gallon version that is hooked up to the shop vac.

I can give a fairer estimate of function after a couple of months of heavy use, but for now, it is looking good. I definately prefer having the TS, jointer, planer etc… running from the dust collector instead of the shop vac… I can definately notice that the air in the shop, and the equipment are MUCH cleaner this way….

Hey that thing sucks very well

Ugh… I was wondering who was going to tell me this project sucked… I almost wondered if Phil was on here (Phil Thien the guy that came up with the baffle design)...

I am on the first full drum of sawdust, and just barely have a dusting in the bag of the DC. Less than 1/4 cup of material, and this is after knocking the filter down. (I don’t have a flapper, so I simply drum on the filter when I shut the DC down).

Not sure, I haven’t measured it, but the guy to talk to on those specifics would be Phil Thien. The designer / inventor of the baffle / separator. I CAN tell you from an unscientific measurement, adding the Thien AND the Wynn filter to my DC, it pulls a LOT harder than the stock DC… I am sure the Wynn had a lot to do with it, and I am relatively certain the Thien slows it down a hair, but the impact is negligible…

Phil is active on Sawmill Creek, and BT3Central (BT3Central user ID cgallery). I haven’t seen him here, but he is probably lurking…

kunk: I’d love to see those readings in addition to some taken through different kinds of tubing, such as flex and 4”/6” PVC (as well as how 22.5/45/90 turns affect it).

I wish these forums didn’t change formatting on us so I could do some text columns and rows to show you side by side comparison. So bear with the choppiness here…

Dust Dog pros. #1. Designed specifically for exact machine fitment instead of “universal fit”. #2. Built in Beater paddle.

Dust Dog Cons. #1. 2 micron filtration rating. #2. Cost (they are more expensive than the Wynn from what I have seen.

Wynn Pros. #1. “Universal” fit, meaning it is a bit more adaptable to a wider range of machines. #2. Spun Bond poly 1 micron filtration, paper blend and nano fiber .5 micron filtration. #3. Excellent “dust release” in the spun bond element. (I simply gently tap the filter, and dust that got to the filter simply falls into the lower bag, no paddle needed.

Wynn Cons. #1. “Universal Fit”. Some machines require creative fitment to get the Wynn to go on. This can be a pain. Also the look of the filter doesn’t exactly line up with the lines of many machines. Aesthetically they aren’t real pretty… #2. Lack of beater paddle. A lot of folks like these, and use them a lot… (See my comments above about tapping the filter down…).

With the better filtration, which is what a canister is about anyway…. I chose the Wynn…

Sounds like the priorities are in order. I am somewhat skeptical about air injection as I would think it would push generated dust away from the pickup point instead of driving it to the pickup point…

For now I am running 4”, but my long term goal is to run a main trunk of 6” to 4” drops…
