I've won!In Friday's heats: Remove a stuck and knackered freewheel with an angle grinder, which takes a nice slice out of the hub as well. I was busy wondering what the smell was (a melting shirt) and, lo! bearings everywhere.In this morning's semi-final: Fail to tighten a crank remover properly so that it smoothly strips out all the threads in one easy movement.In this afternoon's final: Cut a rusted cleat bolt with an angle grinder. The friction, strangely, heats the cleat up so much that it melts the sole of the shoe and I now have a big cleat-shaped hole where the cleat should be.I save SOOOO much money by doing all these jobs myself. :-[
