I recently built this Thien Baffle for my Delta dust collector. I mocked it up in Sketchup and then tweaked the design as I went. Had some scrap marine grade plywood that I used for the top and bottom, which is very smooth and works well. I used 1/8” thick acrylic around the sides of the separator chamber as well as on the top and bottom of the entry transition. My transition isn’t a perfect round to square, it is more of an octagonal to square, but it seems to work fine. Building this baffle with this style dust collector was a challenge, but luckily the plastic collector bag distorts out of the way. The entrance pipe is 4” and the exit is 6” with an air straightener made out of Rockler t-track packaging. I wanted to be able to remove the trash can portion without having to lift the baffle and dust collector so I came up with this wedge design. The trash can itself is attached to a sheet of plywood with a large hole in the center and then I made an angled frame around the outside.
I put weather stripping on the underside of the top wedge to help make it airtight.
The trash can is sitting on a yet-to-be-improved castor wheel cart. The whole thing just rolls under the baffle unit it is wedged tight.
Lastly I added a little window so that I can see how full the trash can is, and what happens to the dust after it falls below the baffle.
All in all, it works well, and is really mesmerizing to watch the dust swirl around while being separated. If you are thinking about building one yourself I highly encourage you to do it. It is not as hard as it looks and can be made pretty inexpensively. Thanks
