4" pipe will carry all the dust you can make and not be in the way so much.
It's velocity that does the work.

I have a table saw, band saw, and jointer in a cluster. It would be
convenient to have one 6" drop with 3 blast gates at the bottom and
then run a short length of 6" flex to each tool. Is there a problem
with three blast gates coming off splits on a single drop? I would
only have one gate open at a time (I plan to have a 2hp blower).
Thanks
