Since I work in my basement, I needed to upgrade from the box fan with furnace filter method of dust control. Then I found out sanding for Intarsia REALLY creates a lot of dust. Saved up and bought a 1HP Delta DC. I am still working the piping but it is functional for what I need for now. The first problem - noise. The basement is unfinished and the wife really does not want to listen to the beast. Plus we live in a side-by-side two family no less. Possible big problem with neighbors. So we built this "out house" to try and limit the sound level. The original plan was to line it with insulation and maybe a drywall barrier. For now, I just lined some of it with carpet scraps. It has a kind of baffle on the side to balance the air and remove the heat. The improvement is very good. Last week I turned it off and grabbed a vac to clean my bench and I wife wanted to know what all the loud noise was. Also, neighbors say they can't here a thing.
If I could have a do-over I would make it bigger. Changing bags etc. is harder than it should be.
