Poor Man's Air Assist...harvested an old vacuum cleaner motor,

Poor Man’s Air Assist…harvested an old vacuum cleaner motor, built a cheap wooden box and sound insulated it with leftover Styrofoam. I run it in series with the stock exhaust fan out the garage door…man, this thing really pulls the CFMs away the beam.

Very inventive!

I tried this with a shop vac, it worked well but was loud. I was warned that the residue from cutting would destroy the motor. Don’t know if that is true or not?

Yep; that’s why I sound insulated it. Besides, it sticks about 6’ out the door. Don’t really care if I blow up the motor; I got it out the trash.
And thanks Kim!
