I have a four bag central dust collector that I use for all of my tools. I
use sprial galvanized pipe and blast gates on all my tools. I reduced the
size of the pipes to match the tool and distance. I don't remember where I
got my specks as to length and diameter. I also found an article in one of
my woodworking magazines from several years ago that is an automatic start
stop for my collector. First I have all of my tools on separate breakers
and this gizmo runs one leg of each circuit through it and the electrical
current that flows when you turn on a tool is enough to acitivate the dust
collector. When the current flow stops on the tool is turns off the
collector. I realize is more than most want to know, but if anyone is
interested in this article, let me know and I will see if I can find it
over the weekend as I did all of this about five years ago. BTW I have my
hooked up to a radial arm saw, 36" drum sander, 24" planer, 6" long bed
jointer, 10" table saw, 12" moulder, band saw, and a 2 speed shaper.
