I don't like to look at this, but its a very powerful reminder of how dangerous a lathe can be, If you are squeamish at all don't look!!! Lathes are a lot of fun but VERY dangerous, give them utmost respect, remember ALL the safety tips, no rings loose clothes that can be caught in the chuck or any other rotating part of a lathe or any machine for that matter.. keep all routers etc, unplugged until ready for immediate use.. this a very graphic link, the guy got his jacket caught on the chuck....
