Being tired of cleaning out the filter in my shop vac, I thought there must be abetter way so I turned to Lumberjocks and discovered dust clyclones were the way to go and there were many different versions of them, on LJ and the internet. After checking out several of them, SimonSKL,woodtooksolong,Jcoulam,Billp, I went with the simplest design. I’m not sure whose design it was, it may have been by someone I haven’t listed , so if it looks like yours, sorry if I didn’t give you credit.
Any way I did change one thing- the inlet to the cyclone. I used a 90degree elbow that I pushed through from the inside until it bottomed out on the edges of the hole I had cut in the side of the cyclone. I had cut the hole starting by drilling a hole to make it posible to get tinsnips in to cut slots. I bent the tabs made by the slots up and cut them to about 1 inch long.I then pushed the PCV elbow into the hole, bent the tabs tighter and put hot melt glue around it.I had to grind a bit off the elbow inside the clyclone as it interfered with the pipe that goes into the middle of it that goes to the vac.
This unit has a permanant location so I didn’t make a base for it.I piped it to each piece of equiptment using 2” PCV and homemade blast gates. I too was surprised how well it works! In the second picture you can see the inlet and outlet pipes configuration if you look closely.
The clyclone is made form a piece of 8” ducting mounted on a 4” PCV base.

Nice job! I like the 90 elbow. I have my vac hose attached at the top and it’s starting to bend over on itself so that elbow would prevent that. I may have to borrow that design element from you :-) Also impressed at your blast gate setup and am surprised it works such a distance!

Great job, that is a lot of work. Liking the blast gates too.
How are you finding suction pressure??
Sweet tip on grounding the unit GW

GarageWoodworks, Thanks for the tip on static electricity, I’ll have to ground it , maybe to an electrical outlet box. WoodTookSoLong and twokidsnosleep, when I turn on the vac.,then pull out the gate for the tool I want to use you can feel the drag on the gate the vac has created and hear the air rushing in. The vac holds all the “closed ” gates tight against one side of the blast gate unit which prevents leaks. System has good suction.

I’m making a Phil Thein version. Gathering the parts now. I’m thinking a 20 gallon galvanized trash can for the receptical. I thought about using a 5 gallon bucket, but figured I’d be cleaning it more than I’d like.

My understanding is that every 90 deg turn reduces the efficiency. I forget by how much, but it was significant…20%??

How did you come by the length of the cyclone? Did you use a formula to determine it or a WAG?

Ron, I just used the whole length of an 8” by 30” piece of ducting.

Sorry Ron, I used 24” of the 8” piece. No special formula.
