possible. For convenience and practcality, it should be placed where it is
convenient for you.

Okay, I did a google, but did not find the answer. For a dust collection
system, where should the blast gates be placed for each machine drop? Six
inches from each machine, or just past the 'Y' coming from the main line?
Does it matter?

Thanks, Jon Oman
