Topic tags/keywords: dust control scms

I am re-arranging my two-car garage workshop to clear enough space to actually park two cars. This means moving my sliding compound miter saw against a wall. To that end, I’m planning to buy a Bosch GCM12SD Dual Bevel Glide ( ), the only saw I know of that can operate right up against a wall.

The machine has a 1 1/2” dust control port that can hook up to my shop vac, but reviews suggest that it is at best 60% effective. I am thinking of building a 6” deep x 30” wide box behind the saw with something like a 4” register box ( ) at the bottom connected to my Oneida Mini Gorilla.

Has anyone done something similar? How did it work out?

Any other ideas?

Actually, the Hitachi C12RSH2 will also operate close to a wall like the Bosch. A fair bit cheaper too and relatively highly thought of. Miter saws are pretty notorious for being messy dust makers but there are some solutions available that I’ve seen that can catch a fair amount of the dust. Here's one solution applied to the Bosch that could probably be adapted to most any SCMS.

I have the Bosch saw and 60% collection is being pretty optimistic in my experience. I hope you will post a picture of your solution if it works well.

Thanks, Ripper, for the Hitachi link and the Bosch video. I’ll get a look at those.

If you don’t plan to move the saw a plywood enclosure behind it might work for you. The best examples allow for a centered spout to go to a split line dust collection. I’ve seen a 4” port behind/below the saws path, and a shop sized smaller 1 1/4” tube to the dust port on the saw. I don’t believe there is a 100% effective plan, but you would be in the 90’s with this. Some then put either plastic curtains, or a plywood front to combat the spray that is just there.

I use my chopper on a mobile base to bring it to where the work is. Using a sled on my TS for most of my critical cuts for length, and miters. I usually just use the chopper to rough cut, and for me 90% of that action is just inside the roll up garage door where I am bringing it into the shop. Much of the time i just let er blow out the door, but for when I do use it inside I am planning this.

A week or two ago Rockler had these for 5 bux off. I bought one. They are pretty collapsible, and to set in a port I am thinking a piece of plywood for a bottom, which would go into the bottom flap. I am having my Wife sew in a rip stop where I placed a 4” hole into the thing.

I guess I saw enough similarity to one of these or the FasCap design, that I thought hmmmmmm, a roll yer own opportunity awaits me. It will probably be Spring, and warmer weather before I get to it, but looking at the others, it’s the same principal.

I currently have a DeWalley POJ straight 12” miter, one sided bevel. In the past I had the pre new Bosch tilting 10 Miter, and loved it. BIL swiped it from me, and he loves it tooo.

I have had great luck in the past using The Big Gulp for a dust chute. Through the 26th PT has them 30% off, pluss if you need any other dust collection stuff you get enough S&H is free too.
