Like many of you, I’m disappointed with the performance of my “under the table” dust collection on my saw.
It is a sawstop pcs saw, and it seems they built a sort of “shroud” around the blade area to attempt to create better suction…in reality, all it does is greatly reduce the airflow.
That said, a big part of the problem with under the saw collection on a TS just has to do with the basic geometry of what’s usually going on during use. Only some fraction of the waste and fine dust winds up anywhere near the hole in the insert where it could get sucked in.
Obviously, there are those above the table guard/DC-shroud things that are the intended solution for this. Somehow, those land squarely in my “just too much in the way to put up with it” zone.
So here’s the idea I had. As stated in the title, it is only partially baked:
It amounts to combining a blower and a sucker to move all the stuff away from above the table.
The “blower” would be compressed air being shot in the general direction of the blade from near the front of the fence and pointing towards the back of the saw. Could be a typical flexible coiled air hose coming from behind the table and mounted along the length of the fence with an air gun mounted near the front of the fence pointing backwards.
The “sucker” would be just an open “cowling” back behind the saw hooked to a DC. Not sure if this could work effectively with the cowling below the surface of the table and just creating a “suction zone” in that vicinity to suck down the debris and dust as it passes by.
My intent would be for this to be in addition to the (weak) under the table collection, not a replacement for it.
Ok, flame suit on. Help me bake the idea, or tell me why I should take it out of the oven and toss the remnants in the can.
