How do you handle dust collection for your miter saw?

On my radial arm saw it was easy to mount a dust hood behind the saw and virtually catch all the dust. Not so, on my sliding miter saw. The miter saw seems to spray dust on both sides of the bevel gauge.

I tried hooking my DC to the dust port on the saw and it works pretty well in sliding mode cuts, but straight chop saw action throws a lot of dust.

I am thinking I’m going to have to build a backstop behind the saw with a 4” collection port as well as running a line from the dust collection port on the saw.

Any ideas or suggestions of how you handle yours would be appreciated.

Hi Cato,
I’m having the same issues, I tried clamping my vacuum hose just behind the blade to get an idea, worked but not well. I’ll be watching, hopefully we’ll get some good suggestions and solutions.

I have a Rousseau stand and I did as you are thinking. I built a sort of hood out of 1/2” plywood and bolted it to the stand. I use my 4” dc on it. The stand has a bottom shelf and I put a shop vac on it that is connected to the saw. Even with both there is still some dust that escapes, especially on angle cuts. It is better than doing nothing.

I built a backstop box behind the saw with a 4 inch port at the bottom. I estimate that I am capturing 90% of the dust. I could probably fine tune my design to capture a little more, but I doubt you will ever find a design that captures 100% of the dust.

One might think that I could run the saw with the port closed and accumulate dust at the bottom that I could clear out later. That does not work very well. You need the DC hooked up and running to effectively capture the dust. The DC creates a down draft in the backstop box that you really need to collect the dust.

ok, so i am currently building a miter wall – I have adopted the new yankee method – sort of – I have a 6” port right behind and under the saw. I also hooked up the top dust port to a 2 1/2” hose – btw I am using the Bosch 10” slider – One way to figure out how to efficiently collect dust is to stand back and watch as someone cuts. You can then observe the dust flow and make something to direct the dust where you want it. In my case the dust shoots below the saws dust hood on plunge and then eventually flows just under the saws dust hood. The down draft from the 6” port behind the saw causes most of what didn’t go into the saws dust hood to curl down into the 6” port. as it is I would say it is at about (not measured mind you) 85% efficient. I plan to make some kind of rubber boot that will further direct the dust toward the 6” port. watch for the continuation of my blog for details – it may take a few weeks until I can work in the shop again – blew out my back and I am recovering…

a month or 2 ago, Curt (blankman) posted his blog about his MS DC contraption which was very cool. you can find it here:

Check out my project miter saw counter. It might give you aonother idea. It does not get every little speck of dust but after cutting on it all day I just blow off what is there with the air hose.

I’ve been thinking of building a permanent version of the Saw Hood behind my miter saw.

My shop is so small that I only have a portable DC. It came with a stand and a large “scoop” on the end for setting behind the tools I use. It works great.

I just checked out the site that PurpLev provided in his comment. That contraption is great. I’m building one of those as soon as I can get to it.

I had remembered seeing the blog a few months back but could not remember who posted it so thanks to Purp for remembering it.
Woodcraft has a sale going on for dust extraction fittings, so i am going to pick up a 4 inch hood, and I already have a 4 inch with a 2.5 inch Y that I should be able to use, so as to accomodate both hoses.

Thanks for the input, now I will see what I can put together. It will have to be a little different from Curt’s to accommodate the depth of the sliders.

Check out the most recent Shop Notes. Mine came yesterday and it features a mitre saw stand with dust collection. I haven’t read it yet, but those Iowans have good ideas. (Go Grinnell!)
