Has anyone found an effective means of dust collection for a compound miter saw? I have a new Bosch 12 inch and with the swing of the saw to 45 degrees in both directions the area of dust distribution is very large. How do you contain it and get it into your dust port? Any suggestions and/or photos would be wonderful. Thanks in advance for your help.

Dale I have my Dewalt CMS on a cabinet, I took a spare dust collector hood (I think I ordered it from Grizzly to install on my tablesaw, but it came with one) it is fitted with a 4" port and is about 12"x12", I drilled it out and attached it to a 16" piece of 2x4 and clamp this behind the saw. It seems to collect about 80-90% of the dust and also seems to keep the rest of the dust from scattering as widely.
Good Luck JK
I have a shop built hood that slides on 3/4" black pipe for miters. It's hooked to a 4" duct on the bottom and a 2 1/2" hose on the top of the saw. Here's a couple of pictures.

Not a 'V' as I suggested but looks like it would work better en' OK!
Here's my favorite design (so far):

Look for the "Don Evans" posts for more pictures.
I like Alan's sliding box idea.

PS: Take a look also at Maia's set-up in this Knots thread. Note especially attachment biggulp4 which shows the under-the-saw collection, something I'd not thought of.

I have one of these from Rousseau:

It works pretty well. I attached a short length of vacuum cleaner hose I had lying around to the dust port on my Makita SCMS so that the dust the saw collects is shot more directly into the hood. The thing is a little on the pricey side though. I don't regret buying it, i just remember being surprised at its cost at the time I purchased it.
I've seen these at the shows, and one retail place. Was astounded at the price! Sheesh! Almost as much as I paid for my Bosch 12" CMS for Pete's sake. Only thing I can think of is the initial manufacturing run was so small they had to really hike the price.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)Another proud member of the "I Rocked With ToolDoc Club" .... :>)
I think I probably have the same Makita (1013?),Did you ever try hooking a vac directly to the port where the dust bag is attached? I've done that on job sites where cleanliness is important, and it works pretty well. At least it keeps the dust from spraying all over the room. But the reason I ask ---- does the shroud from Rousseau do any better? Also, do you connect it to a vac or your regular DC? Finally, when you are mitre cutting to the left or right, do you have to move the shroud -- or is it big enough to accomodate the swing (either to the right or left)?********************************************************

Yeah, I have the 1013 too.
Did you ever try hooking a vac directly to the port where the dust bag is attached?
No, never did. I picked up the Rousseau table and downdraft not too long after I got the saw, so I lived with the dust for a while and then went this route.
-- does the shroud from Rousseau do any better?
So I wouldn't be able to compare, but I can say the downdraft does very well. When I first got it, a few times, I'd be in a situation where I just needed to make one cut and I'd think "why bother to turn on the DC, it's not gonna make that much dust." But I quickly saw that even one cut made a good bit of mess, and that the mess was pretty much eliminated - especially the fine stuff - with the downdraft on. I use it for every cut now.
do you connect it to a vac or your regular DC?
I connect it to my Jet 1.5 HP DC.
when you are mitre cutting to the left or right, do you have to move the shroud -- or is it big enough to accomodate the swing (either to the right or left)?
Mine is mounted on bars that attach to the back fo the stand and moves very easily (without having to do anything but grab the edge fo the hood and put it where you want it) for optimal positioning no matter what cut one is making. I assume the one in the stand would be equally easy to move.
Thanks for your reply.You mentioned "bars" that you can use to slide the shroud around for mitre cuts. I assume this is an integral part of the system, and the shroud is sold with the bars. Right?Thanks again for your help.********************************************************

Yes, the bars come with the hood, just as the roller stand comes with the hood in that version of the downdrafter. The bars are intended for use with the Rousseau rolling miter stand (2875XL). Hope this helps.
It does........... thanks.********************************************************

Geeee.
Make a BIG old 'V' shaped thing with a hood back there ya hooks the vacuume up to.. Not that hard! Get most BUT NOT ALL!
I built a light frame and covered it with (can't remember the name of the stuff) plastic cardboard. The front of the frame is even with the fence. A 4 inch port at the back collects the sawdust.
Works ok. I think the dust it doesn't pick is is what is kicked back off the saw and the fence.
You might think about putting a DC outlet underneath the saw (see the pics from my post above). Unless you're using a really tight throat insert, it would pull alot of the dust down and out.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)Another proud member of the "I Rocked With ToolDoc Club" .... :>)
Here's a shot of what I put together. There is a small shop vac sitting under the bench with a 2 1/2" hose fixed to the bottom of the shroud. Sure does solve one dust problem in the shop. Now about the forty-seven others...
Is that chain on the floor for you dog? Boy you must have a really big dog. :-)Mark
Measure it with a micrometer, mark it with chalk, cut it with an ax.

NICE! I think it would look better using Cherry wood!

We trained hard, but it seemed that every time we were beginning to form up into teams, we would be reorganized. I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency, and demoralization.
