Router bit in a drill press, trying to round over the edge on a small bit of wood. Of course the wood got snagged, and pulled my hand underneath the router bit. Somehow ended up with only a row of flesh wounds across my fingers. Could have easily broken some bones or sever some tenons.
I tell people I got into woodworking with traditional hand tools for the craftsmanship, but it's actually just a fear of my hands getting wrecked by power tools.
Power tools are always the scariest. Machining tools even worse.
You got off super easy if it didn't suck your flesh into that cutting bit. I've seen the videos of people being wrapped up completely on lathe spindles and milling heads in safety presentations and it is NOT pretty. Don't wear long hair or loose baggy clothes around the shop!
