I have been wanting to get a trash can separator for my Harbor Freight dust collector since I bought it. I still don’t have the separator built, but I did make a great improvement to the unit, IMHO. I’m sure many of you have seen the stovepipe mod, or the Delta collector with room underneath the blower for a separator where the motor and the ring are in line. I wanted to try the same thing on the HFDC.
The challenge is that the DC motor is really heavy and I wanted to keep the unit portable. I would guess it weighs 50 pounds. I racked my brain for a while on how to come up with this support system for the motor without building a huge contraption. I used only materials that I had on hand (old door for the bottom, misc 2x’s and plywood for the support) so it’s definitely not pretty, but it works! The 2x’s and plywood are glued and screwed to each other. The whole unit is bolted and lag screwed to the base. I am going to paint it, but that’s about all I had planned for improvements. I’d welcome any suggestions for how to improve the design/functionality.
After some trial and error on the alignment, I bolted down the motor and got it lined up nearly perfectly with the inlet on the ring. I cut a small section of the flex hose that came with the unit to cover the almost none existent gap. Now that the blower motor and the ring are in line, it makes a HUGE difference in the suction. I mean HUGE. As soon as I get a chance I’m going to get the separator built (ala Thien) and put the can under the motor. I’ll have more updates then.
Here are the pictures:
Thanks for looking.
