This incident happened back in September. I took photos at the time but forgot to post them. I just was reminded of it when reviewing old shop photos today.
I have a Ridgid table saw with no riving knife.
I know better, but once in awhile I want to rip a short piece. This one was about 6in long. The photos should tell the story.
I can’t recall now if I was wearing the full face shield or safety glasses. I was using the guard, which kept the projectile low so that it struck me in the belly rather than in the face. No injury, but a warning all the same.
To reconstruct what happened, I show the pieces as they were before I ripped them apart.
The guard was down like this.
The cut completed without incident and the keeper piece (against the fence) was pushed clear of the blade.
At this point, I had the not too bright idea of using the push stick to flick the cutoff piece away from the blade, while the saw was still running. If I had turned off the saw (as I usually have done) and waited for it to stop, there would have been no problem.
Unfortunately, my touch was off – and instead of pushing the piece away from the blade, I pushed the near end of it away from the blade, causing the forwared end of the cutoff to rotate into the back of the blade – resulting in the kickback. For the photo, I’ve raised the guard (which was down in the actual incident) to show what happened. The blade picked up the piece and (especially since it was trapped under the guard), began to fling it toward me.
The cutoff continued to rotate as it passed over the blade (under the guard).
This is the resulting cut on the bottom of the cutoff.
6 inches is too short to rip on my saw!!!
Pieces to be ripped need to be long enough that the cut off piece will reach the splitter, which will restrain it from rotating into the back of the blade.
