Let me know how it goes and don't forget to test with some dark powder in the bottom bucket afterwards... it will help let you know if you are getting debris from the top or the bottom.
Thank you very much! I am very glad it can help people, especially ones that are starting out with dust separation and don't know which rout they want to go.Taf,
You did a thorough job with your experiments. Very well done.
I have been using a Dust Deputy in my little shop. I have a picture of it in my photos.
Your post is a good guide for woodworkers who are looking for help with sawdust issues.
Glad it can help inspire. Looks like you are already pretty close... add some slits right against the sidewall of the bottom of your bucket and seal over a container and you will basically be there.This is GREAT!!! I just started out on this path over the weekend and built a simple 90 degree in and strait pipe out to collect fine sanding dust. Mostly so I don't have to knock out the vac filter every 15-20 minutes. Worked for Chips but not really for dust. I'm going to follow what you've done and experiment a bit myself. Thanks!!
This is a nice modification to the Thien baffle, separating the slots vs. one long slot. Just to be fair, what you built to test the Thien baffle was similar only by the shape of the baffle. As you pointed out to Darkbreeze's original build the thick support around the slot openings will not separate very well. This is true with the Thien as well, but your test used a thick board for a separator baffle. But even worse for me was the observation of the big fat wood baffle flopping around in the bucket unsecured. I was shocked to see it was able to separate 50%. I am sure if I cut a piece of wood with spokes (like your separated openings) and let it float in a cyclone of dirty air it would have very poor separation. Other than the slot separation, your separator is the Thien. You built the taller version that many followers on his forum have built. I'm not quite sure if you purposely made a sloppy Thien for theatrics, but I have a Thien bucket build attached to my vac and it performs excellent. I see the difference between the two as your design requires two buckets and is taller (not good for portable units), but does not require the hardware to rigidly support the baffle to the lid. The other benefit of your build is you don't have to pay attention to how the baffle slot is aligned to the intake (which your test unit ignored as the Thien baffle floated around). The other benefit is using the bucket bottom for the baffle eliminates having to cut out a round disc and then removing the slot from that disc.
If I ever permanently mount my sop vac I may give this build a try.
