A good thing to do in 2014 involved capturing the sawdust thrown from my DeWalt RAS. This solution is stolen straight from “hjt” here on LJs. The key for me was using the Irwin expansion bit to get the right-sized hole in the backboard:
Scrap pine on three sides, cut to work behind the saw’s rear fence. Also low profile, to ride under the motor.
Connected to a very small shop vac.
A little bit of silicon caulk sealed the inside of the box and a small bead was laid down between the box and the saw top. Total cost was $0, and this ‘catches’ the vast majority of the wood chips that fly straight back from cross cuts. Big improvement!
As always, thanks for looking.
