3D Printering: The Combo Machines Cometh

There’s only so many ways to squeeze hot plastic out of a nozzle, and eventually witnessing the explosion of 3D printer designs over the past few years gets just a little repetitive. What then, is someone who dreams of a technological utopia, Star Trek replicators, and making a few bucks off a Kickstarter to do?

The answer, of course, is a combo machine. Where the Repraps, Makerbots, and the very high-end Stereolithography machines can only do additive manufacturing by laying down plastic or resin layer by layer, these combo machines can also remove material, be it plastic, wood, or metals such as brass or aluminum.

Turning a 1942 lathe into a functional piece of art

A couple of years ago, [macona] picked up a 1943 Monarch 10EE lathe. This monstrous machine is not only an amazing piece of engineering but an awesome work of art; not only can this lathe manufacture parts with exacting precision, it’s also a wonderful piece of machine age design.

The Monarch 10EE lathe was extremely high-tech for its time, and the War Dept Detroit Ordinance District tag on the cooling pump bears this machines lineage: this lathe was most likely used to make very precise military equipment such as the Norden bombsight.

After 60 years of faithful service, [macona]‘s lathe picked up several coats of paint in different colors and generally fell into a state of disrepair. [macona] spent a great deal of time overhauling this lathe by replacing a bent feed rod, troubleshooting the motor problems, and eventually replacing the whole motor with a modern AC brushless servo. You can check out the improvement the AC servo made in a video after the break.

Of course no post about a rebuilt lathe would be complete without a few beauty shots. We’re extremely thankful for [macona] for not only restoring this machine, but also for sharing it with us. Thanks to [macona]‘s restoration, this machine will hopefully be around for another 60 years.
