John, I was wondering... I'm sure you have one main dust port right under your bottom wheel to catch most of the dust. Would it help if there was an additional 2" Y or so with a port right on the drive wheel to catch the stuff that travels with the belt. Trying to plan my setup, so I've got a big closet of sorts framed out that will hold my new compressor and a dust collector. It's on the opposite side of the wall from my 2x72, surface grinder, and sand blasting cabinet. That's really the only tools it will be used for, with maybe a dustpan port down on the floor. I'll probably put a T in before the filter so in nice weather I can just exhaust it straight outside.
yep i have a "funnel" which is actually an 8 inch or so floor register duct directly under the wheel / platen where most guys put their water bucket.
i wouldn't even worry about a second inlet on the grinder. not enough rides the belt to worry about. i have to do a bunch of grinding to get any dust to build up on my bench.
i have a second inlet under my disc grinder. each inlet funnel has a slide gate (shutoff) so that i can maximize the suction at the machine i'm working on. that's another reason not to have extraneous inlets around the grinder- it would rob cfm from the primary funnel.
i originally intended to blow the dust right through the wall and forego the collection bag altogether. I still may do that, but i hooked the bag up to buy myself time to make a port through my wall and was shocked by how well the bag worked. It worked so well i never got around to busting a hole in the wall.
