I was wondering if someone can give me a straight answer as I'm upgrading from a 4" to a 6" system. Do the Blast gates go as close to the wyes as possible so if you have multiple branches the DC is not wasting suction in all the unneccasary bits of hose? I've been trying to find a straight answer on this as some people have them on the machines and/or step down to 4" at the machines (which Bill Pentz advises against).

Shep, I put my gates fairly high, just so I don't have to bend over to open and close them. The tablesaw and jointer are on the same run and the tablesaw is a little bit high, so it could be above the Y where the pipe goes to the jointer. Don't know as it really matters about the leaks. If you use plastic, it fits pretty well, I used spiral pipe and just put duct tape over the joints. That is after putting screws in. Don't put any screws on the bottom of the pipe, causes pipe to plug. On my tablesaw, it only had a 4" opening, so I Y'd it to 2 4" and used one above the table. If it doesn't clean out the cabinet ok, it has some thin strips plugging up the pipe. That's the only plugging I've had on my system.

IMHO...the gates should go on the wyes or as close to the wyes as possible to eliminate as much dead pipe as you can in your system. It's not a deal breaker one way or the other so if you need to put a gate close to a tool to be able to reach it better, then do it but the system will function better if the gates are close to the main runs and there is a minimum of dead pipe.
