This is a picture of the dust collection pipe. I'm not sure what to use to connect to this. OD is about 2 1/16 and ID is about 1 15/16. So it's not '2 inch pipe'. How to best connect this to the 4 inch intake on my Powermatic dust collector? And while I'm on the topic why is so much dust collection gear concerned with 2 1/2 inch pipe?
