Sometimes the simplest of things go very very wrong.
I was building a door frame this weekend and while I was cutting the rabbets in the jambs I had a hell of a wreck. I was pushing the wood against the fence with a push block, above and slightly behind the blade, and the jamb must have tipped away from the fence because suddenly it kicked back slightly, sending the push block into the blade. I guess I was caught off balance because I let go of the block as it was thrown back towards me, sending my left hand into the side of the blade.
At that point I decided that the best course of action was to run circles around my yard, top speed, screaming my head off.
After a few minutes I finally gathered my wits, wrapped up my hand, and phoned my folks. Then I commenced the circle running until they showed up and took me to the ER. After almost fainting and damn near puking I was laying in the trauma room, nurses and doctors running around saying incredibly reassuring things like 'yow, what a mess' and 'I don't know if we can even stitch that'. At one point, while the doctor was giving me one of eight 'blocking' needles in my hand (which hurt every bit as as bad as running my hand into the blade) a nurse ACTUALLY asked me 'on a scale of one to ten, how bad is the pain?'. And then I called her bad things...
Anyways, after the smoke had cleared it wasn't really that bad - considering how bad it COULD have been. It took 65 stitches to close it all up, and I lost a tiny piece off the top of my pinkie and at least two of my nails are long gone, but I didn't sever any tendons and I didn't lose any digits. Phew!
After I got back home I went into the shop, turned off my still-running saw, and surveyed the aftermath. The thing that I was left with was this: I wasn't doing anything precarious or unusual, I wasn't using the machine in a way it wasn't intended for, and I thought I was taking the necessary safety precautions. It all happened instantly, there was no time to counteract the inevitable. The last couple weeks have been rough, I've had a couple crappy things happen and have had a lot on my mind. I was working on the door frame at a dogged pace and my heart wasn't in it - I should've just walked away. Inattentiveness caused the accident. It would have been just as easy to lose a finger, or a whole hand, I got away lucky with 65 stitches.
The pictures below are pretty gruesome, pan down at your own risk.
