I just installed overhead dust collection via a 2.25” x 10’ flexible
tube shunted into an overhead 4” dust collection pipe. My saw
already has good dust collection through the bottom, but
perhaps owing to the high arbor speed it kicks up a fair
amount of dust on top. I’ve had it long enough that I’ve
forgotten how much topside dust I had with other table
saws I owned.

I’m pleased to report that the overhead hose captures perhaps
80-90% of the topside chips and dust.

So there’s another reason to use a blade guard – less mess and
cleaner air.

The hose is tied up by a piece of bootlace. I move the saw around
on a pallet jack for different cuts on larger parts. The length of the
tube and bootlace arrangement should provide an adequate
range of movement for most of my cuts.

The end on the hose has a stepped adaptor I got a Lowes awhile
back. I think it was like ten bucks and I bought it for something
else that didn’t work out. I had to shorten it and bush it out
with tape to make a friction fit in the hole on my saw guard.
I don’t especially recommend the stepped adaptor because it’s
overpriced for this application, but it works ok.

I got the hose and 4”/2” fitting from Woodcraft.

I’ve got a SawStop with the dust collection blade guard, and I hook that up with an arrangement similar to Loren’s except that I use a standard shop-vac hose for the drop. Without a hose connected that blade guard shoots a lot of sawdust out the back of the saw. However, the guard does not work so well for skim cuts – those spew pretty much all the dust on the top of the saw, and on me, depending on where I’m standing for the cut. I’m still experimenting with a fixtures to capture that. It uses a 2nd drop.
