Dewalt Miter Saw Zero Clearance Insert

I finally made a zero clearance throat plate for my Dewalt 12” chop saw. I don’t know why I never did this before. A scrap of 1/4” mdf worked well. All it took was two layers of tape on the aluminum rim under the insert to bring it flush with the table.
I always used a plywood fixture that screwed to the miter saw if I needed a splinter-free cut. That worked fine if you were only making square 90 degree cuts. This zero clearance insert moves with the table – just like the factory insert- so you can cut at any angle.
The limitation is that it will only prevent splintering on three sides. You can still get some minor imperfections on the edge of the board against the fence. Still, an improvement over my old fixture for most cuts.
-Cheers

If you clamp a piece to the fence you’ll hav no tearout at the fence and you won’t need to turn on your laser ether. The cut at the fence shows were the blade is cutting.

I used to screw a piece to the fence but now I clamp it so I can reposition the MRF/MDO when I need an angle. Make sure and have it a little long to start with because you use it up fast once you start flipping back and forth cutting angles.

I wish they made insert from heavy metal, it would stay flat.

Thanks for the idea. Got a new 12” slider and was going to use the full fixture backing but will give this a try.

Pinto, I’ve been meaning to do this too. Maybe this will motivate me. :) Thanks for posting.

@ Steven H – Right before you change your blade or get it sharpened, fashion a thick aluminum insert, cut it, then send your blade off to get sharpened. Actually, that sounds like a great idea. Well… I think a nice thick wooden one would be just fine.

Looks a good idea – and your adjustable left side back guide is pristine (unlike mine – which I forgot to move when doing a bevel cut LOL )
