Whoa - close one tonight. I was roughing out some bowls, and decided at the last minute to put down my cage. Halfway through the next bowl, it came off of the worm screw. It's smacked against the cage and lodged against the tool rest. I was taking too big of a cut. I drilled the hole too large because I'm an idiot. I duon't know for sure if it would have hit me but I do know I would have needed new underpants if that cage wasn't down.
