Thanks for the reply. I see you have a blast gate at each machine. So I assume you have a vacuum hose attach to each machine, if this is true how far away can you pull the vacuum with the 6 hp. Also what size hose or pipe are you running Sorry to bother you again I am always trying to figure out a better method for the dust.
Chuck on the vacuum system - I have a Ridgid vacuum with a 6hp max vacuum and it has a separator in front of it. I have never had a problem with this system and it pulls at least 90% of the dust from each machine it is attached to. There is a blast gate to each machine so the only open gate is the machine I am using. The separator collect about all of the sawdust and saves me a ton of time not having to empty the vacuum. Hope this helps - also if I did not mention it - the system can be purchased at WoodCraft.
