A month or so ago I built a miter saw station from plans from The station is great and I’ve used it for several projects but the only problem with it is it has no dust collection so I set out to remedy that situation. The collector is made from 1/2 Maple cabinet grade plywood and a 4” port for my DC hose, It attaches to the saw base with star knobs and “T” nuts. The collector hood is slotted for easy removal and installation from the saw base. I tried to reduce as much weight from the hood as possible for easy transport and it came out very light. I also had some clearance issues I had to deal with both for the saw for full range of angles and clearance between the hood and the wall which is why I have the port attached to the bottom. All in all it came out very well and captures 90% of the sawdust exiting the saw. Thanks for viewing!

Interesting project and I will use the idea for that big 12” HITACHI slider some one gave me .
Nice job and should help with the dust problem we all have to deal with .

Very good design. Seems simple but looks like it’ll collect most of the dust, good job!

looks good, I have tried to come up with ideas to capture more dust off the miter saw. I have the same DeWalt saw and I have notice the alot of dust hits the area behind the saw blade and comes right back out of the front of the saw. The vac port is to high to catch this dust. Just poor design on this saw.

I built several of these but I never had one working really well.
I am in the process of finishing another one after replacing my miter saw.

Ditto what Hillbilly said – very helpful post for my someday-RAS-hood build. Thanks!

I have a project in mind to lock down the mounting plates on my B&D folding miter saw stand. I need a good dust hood for my Chicago Electric 12” slider once that is done… I need something that can be stowed easily to get the miter saw, stand and hood out of the way when not in use… Sadly, due to the sliders rails, it would have to be a BUNCH bigger…

Doesn’t look like your saw is a sliding m/s. And since it’s not I bet it collects more dust than a sliding saw. I made something similar, almost identical, for my sliding compound M/S. But mine doesn’t collect the dust very well. It will pull the fine suspended particles out of the air if they’re hanging behind the saw and under the hood but there is an equal amound of dust that doesn’t get collected. I even made mine out of melamine so, in theory, the dust would have nothing to cling to and get sucked right down the vac tube. But it still only does a marginal job.

Specifically for the Dewalt CMS that I have, there is a tendency for the dust to collect just behind and to the side of the blade but by adding rubber flaps on the rear support frame behind the blade guard and the saw bed this directs the dust more towards the dust port on the saw and increases the flow of the dust into the saws dust port. While there is some inefficiency in regards to dust collection for miter saws and RAS to be able to collect the dust in a somewhat confined space such as a dust hood is a huge improvement over the standard configuration having no hood at all. What doesn’t make it into the vacuum is collected within the hood case and can be vacuumed out later with a crevice tool attachment. A perfect solution would be to collect all of the dust and have it sucked into the cyclone or shop vac but in most cases this is not possible due to the physical characteristics of open bladed saws without an attachment that may interfere with the saws angle or bevel functions. Thanks all for your comments and observations!

Looks like a good design – I have a Dewalt sliding miter saw that this design will work with with a little modification – thanks a lot
