Ya it's nice to see some of us are into making our own tools. I have made a few myself, and you get great satisfaction from it, when all works out good and the tool does it's intended job as good as or better than a store bought tool.
I have a mechanics bar i built over 30 years ago in high school, it has really come in handy working on the car I'll tell ya, over the years. I have used it for prying and pounding off ball joints and other stuff..!
