Shop-Built Dust Collector

It occurs to me that I’ve been making a bit of dust in the garage. Having a beard means dust masks are useless. So dust collection is in order. I could go buy a dust collector, or, as my dad suggested, build one.

So, build, I did.

It’s a rather straightforward project. With, for me, the most challenging part being just wrangling the super-cheap, 11-ply 3/4” poplar/birch plywood onto the tablesaw.

I set to cutting out the sight window (poorly) with a jig saw. I wasn’t at all pleased with the results, so ordered probably the cheapest router and set of bits I could find on Amazon.

Much nicer result.

And the router came in handy for mortising in hinges.

Next, it was on to a few 2” PVC fittings and a few couplers. I didn’t see any need to glue any of it—it’s all under vacuum.

I ran the PVC up to and across the ceiling, leaving myself a few Tees to add branches to it later on.

The Shop-Vac has great static pressure but rather low velocity. Plus, it’s sucking all of the air through a two-inch tube. Add in the cyclone, which constricts it further down to about 1-3/4” or even 1-1/2” and there might be some issues. A proper dust collector with four-inch ducts would move far more air and would be quieter.

Still, this works well enough for now and I’m making some plans for the vacuum in a few months—a hush-cabinet.

Oh, and the part that’s really cool for me—aside from having less dust to suck into my lungs—is that I’ve never built a cabinet before, and I think this turned out rather well.
