I am a frame builder AMA

I have put the hot end of the TIG rod into my mouth by accident more times than I care to mention

I slipped with a jewellers file and stuck it into my face, somehow in a nostril. That bled really badly.

Also, got a 30cm shard of carbon stuck in my hand, one end going in at the bottom of my palm, the other end coming out between my fingers on the other side of my hand. Felt a bit like what a cesarean would feel like id imagine. Stupidly I removed it myself, risking it snapping off and having the have my hand operated on. I no longer wipe carbon tubes down using the 'bash the bishop' method.

As is often the case, it's not the terrifying machines that can rip you limb from limb that get you, as you are always respectful around them, but rather the little things that you cut corners on that leave you bleeding.
