It looks like Dennis, has his question answered. So if I could add one more question on this thread to save starting another. I have 25 year old version of this Grizzly collector:
http://www.grizzly.com/products/1-HP-Dust-Collector/G8027
Would this machine be big enough to handle a collection system in a 20x28 shop? Right now it is used on the planner and sometimes on the table saw. I have a Shopvac that I move around for my small tools. Can't afford a bigger machine and afraid to spend the money for ducting, gates, fittings if what I have can't handle it.
Thanks guys.....
