What garage gadgets have you come up with? Tools, tool storage, flame thrower, etc...
I didn't invent this, but I love it! I was doing some power sanding in my house and I didn't want dust everywhere. This cheap air filter worked great. I have very little dust in my house. This could also be run all the time in the garage.
Box Fan ~$15
20x20" Filter 3 for ~$8
All you have to do is place the filter on the suction side of the box fan. Feel free to tape it up. I use cheap filters and throw them out when they look dirty.
