Someone kindly gave me completely
gratis a copy of the Haynes Bike Book that they had found in their
large book collection.
Some parts of it regarding instruction, are really bad, especially for a complete novice if they read it.
Their method of removing cotter pins, being one of them.
Luckily cotter pins have now been mostly superseded, so there now won't be so many about with
bent-over shafted threads any more.
