    I just had an incident with my GTS1031 Table saw. No injuries thankfully

    Was ripping 8/4 Birch and the whole thing self destructed. Riving knife snapped off with a bang, went into the blade (so much for the Tenryu – its destroyed) and folded the throat plate in half

    No idea what happened. Waiting to hear from Bosch

    Scary as hell – bit shook up

    WOW, that would be terrifying. Glad you are OK Eric.

    Was it a long piece you were cutting?

    About a 5′ length. Taking 2″ off of 6″

    That’s scary. Were you wearing safety glasses? Did the board bind at all?

    Holy crap… Looks like the arm holding the riving knife just completely sheared off.

    Glad you are okay though.

    Sorry to hear you had a scare. How thin were you ripping? Was a thin section between the fence and the blade? Sounds like a binding accident.

    Dirty was just mentioning hours ago elsewhere how he thought the throat plate on the 1031 in his opinion was soft. That may have been part of the problem. Too much downward force cutting something so thick being exerted on plate on a piece that did not have enough support on the platten itself. Plate buckled and everything else was a chain reaction all happening in milliseconds.

    Glad you’re OK, E! That must have been SCARY, now let’s see what Bosch does…
    If nothing else, at least they have an account of what could go wrong with the GTS1031 for future generations of the saw. Again, glad you are not hurt at all. INSANE.

    That amount of damage is insane, this is the first time I’ve heard of a table saw doing this.

    Glad you’re alright man. That’s some scary stuff there.

    I’ve been looking at the photos and trying to figure out what happened. It seems the only way for the riving knife support to snapped like that is if the blade tooth suddenly caught on the part that broke off and jammed, dumping its entire inertia into the arm, and snapped it.

    For this to happen the blade must shift left. The downward nick on front left side of the throat plate support this scenario. The riving knife was wedged to the right of blade from the look of scratch mark on it, which would happen if blade shifted to the left and caught it, throwing it forward and right.

    But what caused the blade to shift left that much though, I don’t know right now.

    That makes as much sense as anything. Still, ripping a 2 inch wide strip off 2 inch (8/4) birch should not have caused that

    Wow that is scary Eric! Glad that you’re ok. It will be interesting to see what Bosch has to say. Seems like a really freakish thing to have happen.

    Whoa Nelly! I would have left a puddle. @Montreal_Medic, Do you think the board had internal stress that was relieved when you ripped it and it pushed on the riving knife after being cut by the blade?
