Radial Arm Saw - Dust collection improvements

When I added a separator for my dust collector, I decided to do something about all the dust my Radial Arm Saw produces. At a minimum, I wanted to improve it. My RAS is installed in-between two cabinets/work tables that run along one of my walls. I also wanted a hook up at the end of the cabinets if I want to attach a hose there in the future.
Running under the cabinets, with a 3-way split under the RAS and then connecting to each side. Four inches on the left with a open vacuum top, and 2 1/2” on the right for a small vacuum hose to help clean up. I used blast gates at the beginning of the hose next to the dust collector, then at the “Y” connector, adding one for each side of the RAS 4” gate below the table, but easy to reach, and 2 1/2” gate on top (visible in photo). The last blast gate was added at the end of the bench and attached to it. It makes for a future addition.
Results – Good improvement, but the RAS still scatters dust everywhere, just less of it.

Sptfish,

Have you tried putting a deflector just to the right of the carriage running from the back wall? That will stop a lot of the dust from making its way to the right side of the riser. Also, a small removable deflector at the front of the left upright will stop some of it from coming forward after it hits the back wall of the collector – removable so you can take it off when you do a miter cut. You might also try a vent deflector from an HVAC system. Part of the issue is that the dust is leaving the blade (straight back) perpendicular to the flow of air from your dust collector (straight down) and it’s blasting right through or by the airflow without getting picked up. Been there; done that.

Dust collection is the one thing I dislike about my RAS. Otherwise, I love it. It’s an older Craftsman that was affected by the recall about 7(?) years ago. I’ve had it for about 20 years. I considered getting rid of it in favor of a compound miter saw. But then I came to my senses. My wife helped. She said no. ;)
