I just upgraded my drum sander to an old Performax Shop Pro 25. I have very good dust collection (Clearvue) with 6" PVC piping, and the drum sander is near the front of the line to the DC. I would like to build a better DC hood for the drum sander. It comes with a single 4" connection, which I am sure is better than nothing, but since I have a Clearvue, I want to build something better.
The box construction will be very straightforward, but I would like your opinions on whether I should build a hood with a single 6" connection or a hood with two 4" connections, spaced along the span of the drum. The larger sanders with a similar footprint seem to come with two 4" connections, but that is probably due to the manufacturers' assumption that everyone has 4" DC piping (a common assumption). Again, since I have a better than average DC system, and I am going to build something, I want to build whichever is going to be better and not have to redo it later.
So, what do you think? Thanks for your help.
