Hi, Since I joined a couple of months ago I have enjoyed reading the answers to many questions I have had. Keep it up, I'm learning.
Here is a problem I had today. I was making a bender to do scrolls and bends from a large wrench. I heated the handle and flattened it enough to keep it in the vise and bent the handle as well to curve it upright. When it cooled, I noticed that the handle was split in several places, sort of how slate splits. What is the reason for this?
