Miter Saw Dust collection hood

I recently redid the dust hood on my miter saw to upsize from my shop vac to my dust collector. I made all simple rectangular box out of 1/4” plywood and trimmed it to fit snugly up against the back of the fence. I also added some close cell foam to help seal it up. The 4” dust port is an aftermarket jointer hood (smallest available) and the 2-1/2” port is from Lee Valley. The 4” port is attached with RTV sealant only. This setup seems to be getting all of the dust that makes it past the fence. There is still a little bit that bounces forward and to the sides but overall collection is greatly improved. The whole setup is held in by the geometry of the fence and the hold down post. (Sawdust in the photos is from before the new hood)

(Also I redid the miter saw station from my last post of it. Shortened it to 6’ and removed the fences. Much happier with this setup.)

Nice job! I like the compact setup and the idea of collecting the dust before is flies too far.

Nick, next to the battle of the bulge, my greatest nemesis is dust collection.

I like your ”low profile sucker” behind the fence.

With a few different kerfed tops, one could cater for most common cuts and for all those odd angles (and compound mitres… which BTW I have never done)... just suck it up manually (as I do now).

You have given me a lot of food for thought and due to the low profile, I wouldn’t be wasting too much timber if I stuff mine up.

Thanks for the inspiration.

Hi LBD. Ya, this works really well. I can count the number of non-90° cuts I’ve made on one hand. For all of my non-compound angled cuts, I use my crosscut sled. For the miter saw I’d just take the dust chute off if I had to make a compound cut. Good luck on yours :)

That looks like a better way to collect the dust than what I have. The limited opening should keep the air velocity higher at the blade where the dust and chips come off. I do a lot of angle cuts on my saw so I would have to modify things a bit, but I think the idea would still work.
