I know this topic has been discussed to death, but after much searching and reading (including Bill Pentz’s site), I’m still not sure how to proceed.
My shop is about 18’ x 20’ with a Unisaw, router table, 6” jointer and miter saw as the main tools. I plan on running PVC for the main duct.
The consensus seems to be to use 6” PVC as close to the machines as possible. The HF collector has a 4” inlet though… must this be enlarged? I’ve read (somewhere) that the main should match the inlet size of the collector.
If 6” is the best way to go, what do I use to neck down to 4” at the collector?
Have any of you used a 4” main? What are you’re thoughts as this is what I had originally planned?
