If you enjoy a bit of DIY in the home or you maintain your own car, caravan, RV, motorbike or bicycle you will, sooner or later, come across something so rusty you think it's welded in place. You dangle from the longest spanner you own, maybe cheating a bit with a length of tube over the end and... SNAP You have a sheared off shaft in a hole... The aim of this book is to provide you with a way to solve the first problem while minimising the probability of the second. It walks you through a series of complementary techniques to clean and free the problem fastener with the minimum effort, risk and damage. Even if you already have a sheared stump to deal with we have techniques for that too.
