Small Thein dust separator for shop vac

I finally decided to build a Thein separator for my shop vac. I think I have favorited every project posted of the separator. I used a 15 gl oil drum for the base. This is a very good size for my shop vac. It werks very well. I used my home made circle cutter to cut the grove in the top lid. Thinking I would have to fasten the lid to the drum I left the lid with a 2” lip past the lid groove. I put weatherstripping in the groove. It sealed so well I didn’t need to fasten it down. Then I also cut the bottom plate. I cut a relief in the lower plate for 2/3 of the dia by 1 1/4 in. I also put some weatherstripping on the outside edge of the lower plate as my drum wasn’t exactly round. I used 2” plastic pipe fittings through the lid. As of now I have used it about a week and picked up a fair amount of sawdust and fine dust. I have about 6in of material in the separator drum but no dust whatsoever in the shop vac. I am well pleased with it so far.

Soon I will build a bigger one for my DC based on a 30gl trash can.

This looks great, Maby add a moble base for the vac and drum together to make it more user frendly. A project that looks and works well is a winner. I like home made tools the best. First class.

Sounds a lot like me with favoriting every separator article. If I can find the room, I want to add one of these to my shop, but I don’t even have room for my shop vac. It sits upstairs in the utility closet and I have to haul it down when the dust gets about ankle high…

Hey guys- Whats better, a cyclone dust separator for shop vac (like dust deputy) or thein dust seperator?
Not in budget wise, but in dust seperation wise.

Thanks for all the comments. Like all others before I got the idea from others. Since building this one I think I can delete all the separator favorites now except the ones for the top hat.

It is in my plans to build a cart for them when I get in my shop. It fits under the edge of my table right now which makes it sorta out of the way. Maybe get a prettier drum not so beat up. The drum was free so I didn’t argue about a few dents.

Concerning the diff in the cyclone and the Thein model I don’t really know. I bought a “dust deputy” and started to use it but it was to tall for where I needed to put my separator so I built the Thein.

I am having an old dilapidated apartment in my back yard torn down and this is where my shop will go. It will be a while yet before the shop goes up but after werking in a 12×20 back porch shop it will be nice to have some room for a change.
