This is a dual-headed hammer I made in MIT’s LMP machine shop. I ran out of time to machine a handle for the hammer, so now it acts as a hefty paperweight on my desk

The central body of this hammer head was made from solid aluminum hex stock. I turned the ends of the aluminum on a manual lathe into a cylindrical shape, before drilling and tapping the holes on both ends.

I then turned down solid rods of copper and steel to match the OD of the aluminum ends. I left a nipple on both the copper and steel which I then die-threaded to match the internal threads of the aluminum. In a future iteration, I’d probably utilize threaded inserts for the aluminum to preserve the life of the threads.

For aesthetic purposes, I chamfered the edges of the copper and steel heads, as well as the ends of the hexagonal stock.
