Hello Friends, Sometimes, even us old dogs need to learn new tricks. Or we need to be reminded by God that you can get hurt if you're not careful. Some time back, I was cleaning the dynamic jaw section of a vise that I was restoring. I had clamped it in my vise to work on (see first picture). While I was wire brushing that jaw section, it slipped out of the vise and crashed onto the floor. Thankfully, it didn't hit me. So I blocked and re-clamped my workpiece in the vise (see second picture). So the lesson here is to test the clamped workpiece before starting to work on it. Any other "Close Call / Lesson Learned" stories out there?
