After fitting the fuel tank that you spent all day finishing....... you dribble some petrol on it which eats through the fresh clear coat.
After remembering to buy that bit of fuel pipe for one of your engines....its the wrong size.
After getting half way through cutting out a new seat base for your trike.......your angle grinder packs in.
After finaly managing to remove the rusted on mirrors from your trike.....you find they are bespoke made and a different thread from any other mirror arm anywhere.
Oh the happy times of a shed builder!
