      I use epoxy, but I take it a couple of steps further.

      If your baffle is still loose, route a groove on the back side(I usually choose a depth equal to about 1/3 to 1/2 of the baffle thickness) that fits the outside diameter of your tube snugly but not really tight, you want a little room for the glue of your choice. Test fit to make sure the tube fits in the groove, then epoxy it in. Once set, I assemble the box, cut out the center of the vent and use a flush trim bit with the bearing riding on the vent tube. This results in a strong bond with the tube being recessed into the baffle and a considerably larger glue area, both at the (butt) end and along the side. I finish it off with a large round over bit. For this to look really good it's important to cut your vent tube with a miter saw for a clean and square end. On painted baffles this can end up looking seamless.

      Also, if you choose to go this route(get it...route), remember to compensate your vent tube length for the depth of the recess.

        Two part epoxy for me! Heck, I use epoxy for just about all my gluing needs, plenty of strength and can be sawed, sanded, screwed, painted, whatever. Fills voids well too.

          Apparently. Either that or some more of the new software goofiness. LOL

            Good morning guys. I know I have seen this topic before but checking to see if any other fresh ideas have surfaced. I have a PVC port tube I want to glue in to my MDF baffle. I will have a double thickness of material at that point. I am thinking I will use a 2-part epoxy for the joining. Comments or suggestions?
            Only thing I don't like about PVC, is the color. I kind of prefer ABS since it is usually black to begin with.

              Wolf turned me on to the black ABS and I used it in my recent Prazise build. Totally agree! Black is better from where I sit.

              The only problem is the ABS pipe doesn't seem to be available everywhere. I'm in the western suburbs of Chicago and my local HD doesn't carry it.
              I had to drive a little south to a different county to find it. I think it's a building code thing in that I can't find plastic electric boxes in my area either.
