DIY Over Arm Dust collector

[Jim Dwight]

Looks good Andrew. The amount of change with the overhead collection looks similar to mine. I was hoping it would get more but it gets most of it, definitely not all.

Thanks! I think to get more you'd need to physically block the stuff that shoots out the side on an open cut. For a closed cut I get virtually no dust on the table top.

I've seen swing down side pieces that seem like they would address the issue, but I'm happy for now with the results I've gotten.

This is an excellent example of side blocking for open ended cuts.

I ended up shelling out for the shark guard, which has been wonderful... BUT... I can't use it with non-through cuts since it mounts on the splitter (rather than to the arm like yours).

What I ended up doing when performing (as an example) dado cuts to produce tenons was to direct 100% of my air flow to the cabinet, and clamp my nearby shop vac hose to the front rail of my table saw. It was surprisingly adequate, but still made me wish for a setup closer to what you have going.

Nice work!
