I think my best bodge was my frame, is cracked just below were the seat was(it was a Saracen Comp 2005 bike.) and my dad and i thought of this stuff which comes as plastic balls in a bag(Y) what you do is boil them in the bag, then u can mould them, but before that my dad used Areldite glue on the frame, then , moulded the plastic to it. Sorry no picture but hopefully u get the idea
