Join me in my manual machine shop where I’ll be making a tiny machinist’s hammer. While my grandfather was a tool and die maker, it turns out my wife’s grandfather was a machinist as well. I was recently gifted a small ball peen hammer that was made by him during his machinist apprenticeship. This inspired me to make my own, but of course I had to put my own twist on it. My hammer will be made of a single piece of low carbon steel (though I would have preferred 4140 steel). I’ll be using various methods on the vertical milling machine, as well as getting into some elaborate (and possibly questionable) setups on the metal lathe. One of the key features of the hammer requires a special form tool. And as you’ll see, I learn a valuable lesson along the way.
