Topic tags/keywords: sawstop brake dado

My son (a licensed contractor) was using my SawStop this morning, cutting some dados in some drawers he’s making for my shop. the drawers were assembled with glue and brads. Apparently the blades touched one of the brads and managed to ground through the brad to the saw frame/top and that fired the brake. The brake is totally hosed – it’s slightly bent, in fact. Te blades appear to be OK Laid them on the saw top (which is perfectly flat and they appear to be equally flat. I’m ordering a new brake, but am hesitant to throw out a set of Freud Dado Kings.

Anyone have any experience with this?

A dado should spread the load out over more blades and teeth than a single blade, so that might have saved it.

I think I have read where Forrest will inspect and repair any damage done on a SawStop brake event during a regular sharpening. That’s what I’d do if I had a SawStop; even on a damaged regular blade. Just get it sharpened.

I think it is an excellent idea to have someone take a good look at the dado set. They maybe able to do a dye penetrate test or something else to see if there are any cracks in the brazing that hold the teeth on.

The last thing that you would want is to throw a tooth out as the blade was spinning.

I feel for you as I hit the edge of my aluminum miter gauge and fired the cartridge. It was only a Freud rip blade and was deeply embedded in the brake. I mounted it on the wall near my saw so that I see it every day to remind me how dumb it was to do that. My grown son was in the shop last weekend and saw it on the wall and asked about it and I had to explain. He just shook his head.

Ditto here … I forgot to tighten the wingnuts that hold the aluminum fence to my Incra and BANG!. Sure got my attention!

I would worry both about the shape of the chippers and blades after such an event as well as any damage done to the carbide tip brazing. Even a slight bend is going to cause issues at speed and the last thing you want to have happen is a carbide tip fly off while using it.

If I could find someone preferably the manufacturer to certify the dado set was in working shape I would probably continue to use it otherwise I would throw it away just to be safe.

As I said, Forrest will fix any fixable blade when sharpening it. They may very well do dye penetrant or magnetic flux testing or whatever they need to determine if the blade is repairable. They will rebraze and retrue the blade as needed. I can’t imagine the company would offer this service if it was not sure the blade was safe when they get through with it.
