Do-it-yourself projects have so many benefits. Many people enjoy woodworking, plumbing or metal working as a hobby. You can save money by doing things yourself, too. And you have the satisfaction of doing something for yourself and knowing it’s been done right (or at least you know how it was done, even if it’s not quite “right”).

But there are some risks. Slivers, minor cuts, bruises and sore backs are to be expected. Other accidents are more serious: cuts from a circular saw, burns while welding or electrocution during a wiring project.
