Make a Simple Dust Collection Box

preview-imageRecently I saw a downdraft suction box used to collect fine dust sanding somewhere online and thought I could make it very simply with 2x4s and plywood. Using some scraps of each that I had around my garage, here’s what I came up with:

Though after production, this came out to be a 7:00 video, you can probably figure out the basics from the picture above. A few details that might not be especially evident come at around 2:00, where I cut two offset holes to allow my Rigid vacuum nozzle to fit properly, and around 3:00, where screws are used in a sort of non-traditional way to retain the top.

Results are shown at the end, and it appears to be somewhat effective, if not “vortex-like.” I should note that this could also likely be used for vacuum forming, where thin material is heated, then sucked around another part. I haven’t tried the process myself, but it definitely seems to have its uses.

For another take on this design, here’s a suction box that looks slightly more complicated to build, but features an angle on the inside to help channel the vortex. Perhaps the results would have been better with that inside. It wouldn’t have been too hard to add to my build, but I was trying to make the simplest build possible (OK, I perhaps the machine screws weren’t that simple) so this is “left as an exercise to the reader.”

I put a lot of work into producing this video, so hopefully you like the results. I started putting things on YouTube to simply host it for this site, but I’ve been trying to put quite a bit more effort into production etc. I’d encourage you to subscribe there to see what other videos come out of “JCP!”

On another note, I’m thinking of changing around my YouTube playlist format to hopefully make things easier to find and play. Please let me know what you think about the video in the comments below, or perhaps via Twitter here! As always, thanks for reading and watching!

  1. Great idea to just repurpose a vacuum. Have you thought of filter media so you could get away with actual dust collection. This box could be a great start.

    • Hi Logan, thanks! Perhaps I’m missing something, but I would think that the Rigid “shop vac” would act as a filter. If you mean an overhead system, not really, but maybe that could be a “long term” goal!
