My original shop went under 7' of salt water in New Orleans last year during
Katrina. I am now setting up a new one on high ground in Dallas, TX.

I have a 20" Powermatic and a Orinda 2 HP Dust Gorilla. I am presently
running the duct work. What kind of shop made collection device should I
use and where should it be located?

For those of you who answered my post about wood face plates - many thanks.
I finally resorted to the telephone and found that the search string had to
be:
1-1/4-8, not 1.25 x 8 tpi or some variation on this theme.
