Hi,

I am building a combo work bench/downdraft table. I have some
questions. I am working off of the design that rockler sells as a kit.
(20" x 40").

I was going to just use two 20" square house fans in a blowers stead. I
have had some success with a ceiling air filter made with a house fan
and some furnace filter. Please keep in mind, I am not looking to suck
the hair off my body, just catch some of the dust.

questions:

1) The Rockler motor looks to have some cool impeller of some kind. Is
this impeller something like what a vacuum has? Are they sold?

2) could a fan blowing from above, down onto the table help?

3) What is a good material for the surface? (I was going to drill out
perfed melamine)

4) I have a 1.5 horse vacuum nearby, I can do better with some fans,
can't I?

Thanks!!

Tor
