..you could've witnessed me running around and screaming like a little girl after I accidentally grabbed a super hot section of rear stay:
That's just the nasty blister on the outside. I managed to burn a good section of my thumbs inner web as well. Fucking. SUCKED. It even made that TSSSSS noise when I first touched it- nnNHYAAAHHAA!! So gnar..
In any case, I feel like no one ever really mentions safety outside of helmets and blinkers. That or it's all about the end product and craftsmanship. The truth is that a good portion of the tools involved in building bicycle frames etc can and will maim you every chance you give them. I'm just lucky cause the burn wasn't that bad. Mostly cause I didn't have to go switch-stance later on that night, hehe. In any case, it was bound to happen..
So no matter what your experience level happens to be- Make it a point to be mindful of your surroundings and careful as fuck with anything that has fire coming out of it or a really sharp high RPM rotary bit attached to the end. Most importantly: USE YOUR SAFETY GEAR! It certainly won't hurt as much as getting your dumbass burnt or cut the fuck up..
Having said all that, try to retain a little more dignity than myself if something does happen and don't let it discourage you from continuing your work!
