Upgraded my dust collection

The dust in my shop was just too much. I found myself wiping thick dust off of tools that I used everyday, so I knew something was wrong. I pulled the top bag off my DC and found what you see in the first pic, I guess the built in ramp just acted like a shelf. The bottom bag was about half filled with dust and the 1st stage can was about half full also.

I bought a Donaldson cartridge filter on ebay for $112. The third pic shows the baffle I made for the first stage collection can. I probably made it more complicated by the way I decided to attach everything, but it is what it is.

For the filter to fit I had to make a reducer and used 2 layers of MDF, one larger than the other to make a tight seal. The picture shows a shadow that makes it look like it has a gap, but it doesn’t. I made some clips to hold it to the DC as well as a few to connect the top cover to form a seal there.

The difference is amazing. I have more suction at every drop and the dust is so much more contained. I should have done this years ago. The worst part of this project was the fact that I had no dust collection while I was building the baffle and other parts and I had a lot of clean-up to do when I was done.

fine business on the improved dust collector system. Just a note on the filter, I bought one simular after a recommendation in Fine woodworking article. It will clog up no matter how efficient the baffle is and there is almost no way to clean the pleats. . I cut a hole in the top to put a pipe and a gate. then with the motor running would use air pressure and blow the dust out in reverse with the pipe through a window. The filters designed for dust collectors the pleats are loose and one turns a lever and it just hits the pleats. I made a set up out side and use no filter, good suction all the time.

Excellent job on re-doing the d.c. That should work just fine…I did pretty much the same thing with my d.c. several years ago…Dust would pile up around the inside rim just like yours…I bought a Wynn filter, and cut a “doughnut” to set on top of the lip with a hole in the doughnut smaller than the inside rim, and it was a little smaller so the filter would sit on it….I cut a channel with a router 1/2” deep for the rubber around the bottom to sit in, then clamped it from the inside…..Made the doughnut out of 3/4” ply…..No more problems….
