How do I get a good dust collection system going for a compound sliding miter saw?

Question

I have a Dewalt DW718 compound sliding miter saw. There is a dust collection vent with an adapter piece at the end to tie into a vaccum system. When I hook my shop-vac up, its gets some of the saw dust, but quite a bit hits the throat of the saw, causing it to spring forward and sideways all over the place.

I noticed that there is a bolt holding the dust collection tube in place. Does shifting the tube into the right position make a difference?

Thanks-

Answer 1

I have to agree with answer 1. Certainly a more powerful shop vac/exhaust system would work also, and usually found in commercial shops.

If you've assembled to instructions and have the space; the "Funnel" idea is extremely effective. I made mine out of Luan initially and not ROUND. It was a box in effect, with larger opening closer to the discharge. The only way I can analogize the look of it is a Pyramid with the top cut off.
At the back end the collection hose fits to the box.

I suspect I'd be more concerned however in what you describe as spring forward and sideways all over the place.

Answer 2

Compound Miter Saw Dust Collection

Answer 3

It will really depend on what other tools you have. For instance I have a Radial Arm Saw so I only purchased a compound miter saw. It also depends on the type of work you will be doing. If you are going to be doing a lot of framing and will be cutting 2X10 or larger stock often a slider may be a good choice.

Answer 4

If you could design one that worked efficiently, industry would beat a path to your door. The way the machine works prohibits the collection of all the dust it produces, all you can hope for is to collect the majority and clean up the rest.

Answer 5

Larger shop vac.

Answer 6

if the saw is stationary, and not mobile, you could build a wooden funnel behind the saw, narrowing down to the shopvac hose. i do this, and virtually no cleaning up afterwards
