useful charts or calculators for working metals and other materials

[Troll Hunter]

Hi, Frank S, thanks for your kind offer. The problem is that I never know what I'm going to need, or know, for my next project, be it repairing a household appliance, fixing something on one of my toys, or just helping a neighbour. For example, if I'm repairing a tear or split in sheet metal do I weld it, patch and glue it, patch and pop rivet it, solder it, or totally replace it. Being a real skinflint when it comes to replacing something that is repairable, having a resource like HMT and the charts you publish is a great help in this sort of decision making. Keep on publishing, I'm downloading and saving them all!
