I've read a great many postings on using PVC pipe for dust collection and I know there are more than two type out there. Can someone list the common names and the trade names for the pipes (such as S&D is ASTM-2729; I'm not sure that's correct even).
In addition, Rockler has a listing for a 4" Hose connector to PVC Sewer Pipe listed (Item 38820 http://www.rockler.com/product.cfm?page=20383) with the description "The large end of this connector fits into Schedule 20 PVC, while the smaller end attaches to any 4" dust hose. The PVC connection requires silicone adhesive and the hose can be fixed with a metal clamp (neither are included). Schedule 20 (PVC sewer pipe) is thin walled PVC pipe commonly found at home centers. Made from ABS plastic." I'm pretty sure that sewer pipe is not schedule 20. Correct? I thought it was for central vacuum systems.
