I recently purchased the Rigid double bevel sliding compound miter saw and just got it set up on my work bench. This thing is a beast and because it can miter up to 62 on both sides, and is double-beveled, I had to modify my bench a lot to accommodate this beast. In fact, if I new how much added work it would be I may have…..

Rigid seems to be pretty popular, so I’m hoping someone here has sorted out a good plan of attack for getting some of the dust this thing produces! I initially tried a full length 2.5” shop vac hose, which was connected to my 4” duct system and it was like I had nothing attached. I did make a few cuts with the DC off, and realized it was doing something! I could have shortened the hose and improved the system, but I wasn’t convinced it was the way to go. My setup on my 12” chop saw wasn’t perfect, but it kept the clouds of dust from accumulating.

As of now, the best I could come up with was some 2.5” attachments to connect to the saw, then I added the wire brace for the dust bag, in order to use it to support my 4” gate and hose. This appears to be a little heavy and it does pop off now and again, which is annoying, but there is so much more air! I also zip tied around the 4” hose to keep it between the metal wire brace, but left it loose enough for the hose to move, while sliding the blade.

I think if I could keep the hose from popping out and get the folks at Keen to start selling their sliding miter saw dust collection kit I would be good to go, but it appears to be on hold and I heard the creator of the products is no longer with us.

If anyone has had any success with collecting dust on this saw, I would love to here it!

There are two ways to attack this problem.
The best remedy is to employ both methods.
1. You need close capture, the dust port you are attached to now, with the high static pressure produced by a shop vac. The bigger the better.
2. You need a hood with the largest volume of air flow you have available, Like your dust collector.
These two types of air flow will never be obtained from the same machine so we are talking about two dust control systems connected to one saw.

Or just take it outside like I do mine and let it blow dust into the yard.

Thanks for the thoughts! I should try the shop vac one more time with a shorter hose but my gut tells me it won’t be as good as the 4” Jose I have now. Both would be ideal!

I thought about building a hood as I’ve seen some nice ones out there but I couldn’t Imagine the math involved in my double beveled 62 degree miter on both sides!

Taking it liaise is not an option as I spent several hours dialing it in to a common fence with precision kit and to my bench.

Surprised there aren’t more products to address this!

I have this saw, some attempts have been better than others but nothing worked really well. I use a big shop vac and dust deputy connected to the dust port behind the blade. I have found that if you pull the blade past the work piece, plunge and then cut pushing the blade in most of the dust is captured. Anytime I use the saw to plunge cut it spews dust everywhere.

Have your say...
