Dust Collector Reconfiguration/Upgrade

I reconfigured my HF DC to eliminate the hose from the impeller housing to the filter/bag assembly. I then built a Thien baffle atop a 20 gal Brute and added a Wynn filter. I also added a hose hanger and a place to hang my remote switch so I’ll always know where it is.

As an aside, I have 2 fire extinguishers in my shop: one at each end. I figured if saw dust catches fire I’ll be within reach of one of them.

Looks very clean. I’m using the “in the can” style of separator, and I don’t like how it automatically puts a bend in the hose right at the connection point. A top hat is on my to-do list.

I also just bought the Harbor Freight collector. I really think I want to go with the Super Dust deputy instead of the Thein. I haven’t even taken mine out of the box yet. It’s only 25 degrees outside and my girage is quite cold.
I like your setup, but with the cyclone, it would be to high for me to mount the blower the way you did it.
I know a lot of the jocks are using the Thein, just wondering if you built it because of price or do you think it’s as good?

Nice looking design, I can tell you put some thought into it minimizing the footprint.

Nice job of minimizing the foot print of your dc system.

Better be careful, I posted a pic of my dust deputy on here yesterday and some guy blew a gasket. he copied and pasted the rules for posting this stuff under finished wood working products. Nice looking DC- Andrew

I don’t suppose you have a drawing with dimensions do you? I need to do exactly that, except no top hat. I have an existing Thien separator based on a 55 gallon drum I need to do this with…

Andrew, there was a lot of wordworking, gluing, and screwing involved in reconfiguring this! If anyone complains then mobile carts, workbenches, and jigs should be excluded as well.

Steve, the Thien seems to work really well. I put handfuls of dust from my planer and TS and hardly anything made it to the bag.

dbhost, sorry I don’t have plans but I could measure if you like. I sort of designed as I went on this one!

How do you get the garbage can in and out? Is it just a friction fit under the baffle? This is definitely on my to do list, but I want to make sure it’s easy to empty while still retaining a good seal.

Well done. I would like to do that also but don’t want to increase the footprint in my small shop.
