I made this dust collector (for only a couple bucks) mostly out of MDF, based on some rough plans I found here.
I used a 7 gallon pail as the base, only because it gave me a bit more room for collecting, and I didn’t have to pay for it!
I cut the circles using my tablesaw (yes, my table saw) using a homemade circle cutting jig like the one here. I routed out a rabbet around the lid so it would create a snug fitting “seat” to sit on top of the bucket. For the baffle’s shape, I used my table saw again to cut out about 1-1/4” from about 2/3 of the circle. Confused yet? A little math comes in handy here.
I used some 6” length 7/16” dowels to create the space between the lid and the baffle. Use a drill press to make sure your holes line up perfectly and make sure you label them 1, 2 & 3 just in case your measurements aren’t dead on (mine never seem to be on projects like this).
My shop vac hose is 1-1/4” so an ABS pipe of this size fits the hose perfectly. I used a forstner bit to drill the hole for the pipe but then had to nibble away a bit more MDF from the hole using a spindle sander.
This separator creates a cyclone inside the bucket and I was very surprised at how well it works!
Things I would do differently next time:
1. Use a drill press to make sure the holes are dead on. I didn’t do that.
2. Make the dowels a bit shorter. Maybe 4 or 4-1/2”.
