Admitting our dangerous (and dumb) mistakes might help others.
When I decided to start this wonderful hobby, I bought on my first trip shopping the following: a table saw, planer, a scroll saw and a drill press. Having no idea how they worked, I unpacked, set them up and plugged them in. I was of course depending on my superior intelligence, so there was really no need to read very much from the instruction manuals. (Yeah right). I yelled for the wife to come down to the basement and see all this wonderful stuff. With her standing beside me, I turned the table saw on to make a cut on a wood scrap. As I pushed the wood, it began to drift a little. Not knowing what was happening, I pushed, the fence moved because I fail to lock it and I cut the end of my left thumb off. OUCH! The blade threw a piece of flesh, bone or nail back and hit her on the cheek. She screamed, I said a couple of really bad words and we headed for the emergency room. Moral of the story is if you are a newbie or been at it all your life most people get in a hurry and get a little careless on occasion. I have heard it said your machines will lay in wait for years just waiting for you to get careless. Be careful my friends. Now, who else will fess up?
