After a lot of looking at what other people have built and seeing what I could buy, I built this today. I used a 20 gallon trash can, some MDF, two 3” flu pipe elbows, and two screw on connectors from Rockler. I made a round piece of MDF one inch bigger than the trash can and one piece that just fits inside the can. The smaller one was screwed and glued to the center of the larger one. I drilled two 3” holes in the underside just through the first piece of MDF and inserted the elbows back to back. I drilled two 2 1/2” holes in the top just through one piece of MDF and mounted the fittings over these. My shop vac is attached to one fitting and the other goes to the tool. It doesn’t matter which goes to tool and which to the shop vac. I figured mounting the elbows back to back would force dust to go all the way around the can to be able to get through the other elbow. In my test it worked great. Time will tell how fast my shop vac filter gets clogged with small dust. This all cost about $40. I had the MDF.

Most designs have the suction pipe in the center (where the dust is not)

It’s interesting you say that, because I was thinking about an hour after I made it that it should probably have been in the center where the dust isn’t. It won’t be difficult for me to move it if it seems I need to. Thanks for the comment.

Mine works well to separate the chips. The fine dust makes it through to the HF dust collector. Thankfully, the Wynn cartridge filter collects it.

It is mostly with planer chips that these setups have
problems. You can run a 4” hose from the planer to
the trash can and the vac hose out and it will work
pretty well for a benchtop planer and most other
common machines in hobby style usage.

I should say that planers make a lot of “chips” and
not a lot of dust. “Dust collection” is a misnomer
for setups that are expected to get both chips
and fine dust. Therein lies the problem. Big
blowers with big motors do a good job with both
dust and chips but anything that runs on 110 volts
may contain modest hobby messes but it won’t
make for a “healthy” workspace.

Stick with what you have developed by all means
but when your nose starts to run a lot it’s a sign
you need to cut back on the wood machining
or upgrade the DC.

I don’t want to scare anyone. Just keep an eye on
the respiratory issues.

Yard sale shop vacs hooked up to every machine
are a pretty good and cheap way to get good dust
collection for modest work loads. Only the planer,
jointer and lathe really overcome shop vacs among
basic machines but this is mostly chips and not the
fine dust you get more of when sawing and sanding.

Looks good. A lot of planers come with an attachment that hooks up to a trash can that works great.

Yeah, my Dewalt has a shroud that attaches on the out feed side, but it still lets a lot of shavings come out the indeed side.
