My Diesel Ball Peen Hammer

About: Awesome Gear I've designed myself.

I made this hammer using a push rod from a diesel engine, a ball bearing, 3/8th steel dowel, and a piece of rubber hose.

Dimensions are ¾” X 2¾” for the business end and roughly 8” X ¾” for the handle.

I cut the rod to size. Then I welded on a ball bearing and ground it down for the bell side of the hammer. I welded the dowel on for a handle and slipped over a piece of rubber hose for grip. To finish it off I beveled the end of the hose.

If your not quite sure what a push rod is, it’s an internal part of an engine between the camshaft and rocker arm. See the link below and scroll down ¾ of the way for more info.

It’s my “go to” hammer for my jewelry instructables; five years old and still holding up.

    I don't have a welder or spare engine parts lying aroung any more. I've seen good looking hammer at The Home Depot and Lowes. That's where I'd buy one.

    might have to check it out because I could use a decent hammer with a smooth end.

    Lowes is my favorite place in the whole wide world...I'll get lost in there for hours. might not send me there..LOL

    This is a great idea. I need a little delicate hammer for when I'm not trying to crush things, and the steel makes a good softer end and the ball bearing makes a good hard end. Hope you don't mind if I follow your lead...

    Well done!

    My weldings are horrible. I have a 150 Amps electric welder, but I am too clumsy.
