OK, being new to using a separator, what’s the biggest Pro/Con to using a baffle and how exact does it have to be for it to work properly. I’ve done some reading on a few sites and I’ve seen everything from Anal Exact to just close enough.

The baffle inside the seperator can.

I am not trying to be difficult here, but you need to explain better what you are talking about

20K plus members

only 1% or less, has my experience, most of those dont post.

just watch the @#it festival to prove my point.

if the tool doesn’t shoot the dust into a port that collects it

its air born and dust becomes a mystery being sucked right into your lungs

Sorry, OK I guess I was being a little vauge. Carpul Tunnel & Arthritus makes me not want to type to much. I just upgraded my Dust Collector and I’ve been looking into making a seperator for it cause the plastic lower bag on the Harbor Freight Dust Collector is a PITA to remove and replace, for me anyway. I just wasn’t sure if the extra effort to use a baffle in the can was really worth it.

Not sure what you mean about a baffle.
I have a grizzly 2 hp dust collector, and a separator lid thing on a trashcan, most everything is collected in the can, so the bag on the collector, very rarely needs empty.
The band that holds the bottom bag on is a PITA to get sealed back up, the trashcan is easy to empty.

skip the baffle and buy into engineering that is backed by science

science ends mystery and BS claims and with that said, ya, ......a baffle is better then no baffle, it seperates the large dust particles from the small ones but its the tiny ones that kill you so its like icing on a cake, the thicker the icing the better tasting the cake for some,.......some prefer cake only.

30 YEARS OF THIS @#IT, ..................aka, dust.

you can decorate a cake, but dust…...............its dreadful. Smells sweet but the smell is short
lived, when the reality of it seeps into every crevice of your life, your partners life, and if so lucky, your clients life. I can assure you, two options out of three go south quick.

Cheers

bubinga, I’ve seen your version which is the one im inclined to make, then there’s another one when there’s a baffle that sit about 6”-8” under the lid and connected to it. If you look at this link it’ll show one.

OK Moron, I guess your saying that a baffle just seperates the bigger chips into the can instead of the bag. So, are you saying that without a baffle only the fine dust would go in the can? Thanks for you patience but not all of use have the knowledge as the next guy.

I think the baffle is to blow the dust toward the side instead of straight down.
The lid I have, the input connection is at an angle, therefore the dust is not blown straight down
I am a very poor typist, so I use Dragon NaturallySpeaking software, with a microphone, I speak it types, and I love it, using it now

I assume you mean a Thein separator baffle. His original was for a metal trash can and his site is fairly specific about the location and angles of in/out ports, also the 240 degrees of side open slot for losing the dust to below …and also where the in/outs are in relation to the remaining 120 degrees.

I, too have seen the various derivations of his baffle that run the gamut of pvc/duct tape and plastic pails to large, heavy wood and metal lobstrosities that appear to be “lets use as much wood and woodworking skills as possible to build this round box”. I don’t want a hernia lifting the lid to empty the barrel or trashcan, you know? There is a genuine lack of sheet metal fabrication being used (or at least upladed to Youtube). Then there’s top feed vs. side feed… below the lid vs. top hat.

Then there’s the separator box as shown in one of the pictures at the Rockler site where they sell the screw-together separator intake and exhaust fittings. The ported wall that divides the box qualifies as a baffle. It looks like it may be a pain to empty, but it feeds into the larger part of the box and shows the most and larger waste, then there is an open port into the smaller section where there is less and smaller waste, then finally the output from the front of that section.

How exact ? At least have air-tight ports and a good seal over or into you collection vessel. If you mean exact from the standpoint of port locations, angles, exactly 240 degree slot 1 1/2” wide, etc. etc. then i would say why not ?

I plan to start with a non-baffled 30 gallon drum with the Rockler fittings. i will use, test and learn from that. Then, almost immediately I will make a simpler baffle that will have an adjustable slot opening (from about 180 to 270 degrees) so I can play and learn some more.

To me, the Thein baffle is like a top cross-section of a cyclone that starts (and maintains between the lid and the baffle) cyclonic-like action without the actual funnel-shaped cyclone. The center output tube is in the eye of the hurricane much like a real cyclone… and the solid matter is being pumped around in a circle while gravity (and introduction of additional matter) forces / drops it through the slot continuously (although not all at once). There are shavings that get to ride around a bit but finally drop through the slot, so it’s not 100% once around and down.

If that doesn’t satisfy me i will venture into true cyclone territory.

If you are really interested in all this, just take a look at the very newest Dyson three stage bagless vacuum cleaner technology and think about how that technology might be applied to dust collection. Hmmm… I wonder?

Bubinga, does the Dragon Naturally Speaking work pretty good these days ? I tried it several years ago (much earlier version) and though promising, it was not impressive. Any problems with it at all ?
