That's what I was calling myself all the way to the emergency room this morning. I was cutting a piece of luan 12x12". I made the first cut with the rip fence for width. The piece was 4 ft. long so I turned it and was going to use the mitre guage to cut it to length so I used the fence to set 12" so it would be square. Well like a DUMMY I forgot to move the fence before I started cutting and well I guess you figured out what happened next. Piece got caught between the blade and fence and shot that sucker like a rocket. It grabbed my right pinky and ripped it open basically from where it attaches to my hand, down both side to the first joint. Peeled it to the bone. It was pretty ugly but luckly it didn't cut any tendons so I can still move it. The piece shot so hard it somehow hit th mitre guage and turned the head from a 90 to a 45 degree angle and it was tight to. I was standing to the side of the blade behind the mitre guage, so it looks like the mitre guage deflected the wood away from my body and it shot all the way to the wall about 10ft. back. Now bfore I get any lectures I know exactly what I did wrong and it was very STUIPID and I hope this can be a lesson for someone else. If you still want to lecture and call me STUPID I'm OK with that cause I prolly deserve it. Just glad it didn't hit me in the gut.
