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”.

You’re going to love what it does for you almost as much as you loved building it. Great project.

I like the simplicity of this and have been trying to decide what I want to do with my vacuums to keep them from getting the filters clogged so quickly.

Not confused, but do have a question or two.

1. The 1/3 that is not 1 1/4” cutout, is firm to the side of the bucket?

2. Why would you make the dowels shorter?

3. Where do you get 7 gal. buckets?

Thanks in advance.

TDominy,

1. The 1/3 that is not cut out rests against the side of the bucket.
2. I would make the dowels a bit shorter just to make more room in the bottom of the bucket. I cut the lower baffle a bit small so I had to extend the dowels so it would make a nicer fit (point #1). No other reason that I would shorten them other than to just make a bit more space in the bottom.
3. The bucket I used had John Deere hydraulic oil in it that my father in law had lying around. You could easily use a 5 gallon pail that you can buy at any hardware store for a couple bucks.

Hope that helps!
