one of the last things to do before using the unisaw i recently resurrected is to find an effective way to manage it’s dust collection at the source. my delta 50-850 is up to the collection task, but the ~’72 vintage saw, with it’s large square opening (yes, i know i have to close this up) and missing dust deflector, seems to present some challenges regarding collecting the sawdust at the point of origin. there is a magnetic starter switch within the saw cabinet at the rear of the cabinet just above the cabinet’s lower detachable base that creates a bit of an obstruction. i’d like to not have to punch any more holes in the cabinet, a la the shanesy restoration video series. i’d be particularly interested in blade shrouds as that sees to be a really effective way of attacking the dust before it spreads into the cabinet. what have owners/users done to corral the sawdust within the saw cabinet so it finds it’s way into the hose going to the DC?

My general feeling, toolie, is that this dust collection for table saws is being way overthought. There’s no way you can protect the innards from the dust, and indeed they’ve been tolerating it for what, over a hundred years?

Dust is not very smart; it won’t slide down slopes until they’re nearly vertical.

You can’t seal up the cabinet and in fact don’t want to; DC needs makeup air. That comes from the louvers in the front door (common) and the gap between the top and the cabinet. If you hook up to the cabinet in that condition, you’re getting about the best you can, and you’ll still have to help the dust and chips along manually periodically.

If someone can do better than that, I’m interested. My PM is hooked up to a 2 hp Murphy-Rodgers and with all the other blast gates close, it gets the dust pretty well but when the chips are down, they stay there.

I agree with your comments. Overall, I believe Dust from Table Saws is the least pressing dust issue within the shop – Miter Saw, Sanders, Hand-held & table-mounted Routers, Jointers, Planers all generate significantly more dust and debris.
It’s not pretty, but can you simply terminate a 4” (main DC run) or Shop Vac hose within the cabinet while you’re running the saw? Most table saw debris is fine, so any air suction would help. I have a 4” main DC run connected to the back of my Unisaw, and dust still accumulates within the cabinet.
