Bike Anti-Porn - When Things Go Wrong

Yeah. Welding is one of the most useful things ever. I've made frames using tig and brazing before, and I'm making a street luge frame at the moment.

Here's a picture of a trials bike frame I made for my A level tech project:

And to prove it worked!

It was fillet brazed from butted 4130 tubing. Rode pretty nicely, but was a bit on the heavy side for competition stuff.

Buy your own welding kit and do it in your back garden, it's the best investment you'll ever make!

that's absolutely brilliant... the fact that you made it at school is even better. Top marks.
