I've been thinking about dust collection a lot lately. My current dust collection method is wait until it settles and clean it up with a shopvac and broom. But I want to improve that with a decent system. I've been looking at the Harbor Freight dust collector with the intention of converting it with a cyclone for separation. But I have also been looking at DIY systems built with shop made impeller (Matthias Wandel and others have good videos on YouTube).

I have an old Hitachi M12V router that someone gave me. It's in rough shape - handles are missing, height adjust knob is broken, I don't have collets for it, etc. But the 3-1/4 HP motor is still good. So I got to thinking... could I use that router motor to drive a shop built impeller for a dust collector? I'd have to use a belt drive with a small pulley on the motor and a large pulley on the impeller. But it seems like it would be plenty strong.

Any reason it wouldn't work?
