I've got an older Powermatic 12" table saw, and whenever I use it with dust collection I need to get down on the floor and hook the 4" flex hose up to a hokey PVC fitting which is just stuffed into the outlet hole in the cabinet (pic 1).
Is there a better fitting I could use? Haven't gotten around yet to doing a permanent setup. Running separate hoses to all my machines because I move some of them around a lot.
Also (pic 2), what do you do to seal up the big opening on the side? Now I use a cardboard cutout I made, which fits around the motor. Does a fair job of sealing that opening, but I'm wondering if there's a better way.

From contributor J:
You can buy a welded flange that can be screwed to the cabinet so that the hose slips over it. Is that the sort of thing you're looking for? I know Oneida sells such things. Looking at those pictures, I think I'd also build a square plywood funnel/hopper sort of thing in the bottom of that cabinet so that the dust falls naturally towards the outlet rather than piling up in the corners. With such a small flex hose, you'll never get any dust collector to evacuate the dust otherwise.
