[This Old Tony] was cleaning up his metal shop after his yearly flirtation with woodworking when he found himself hankering for a nice coffee. He was, however, completely without a coffee making apparatus. We imagine there was a hasty round of consulting with his inanimate friends [Optimus Prime] and [Stefan Gotteswinter Brush] before he decided the only logical option was to make his own.
So, he brought out two chunks of aluminum from somewhere in his shop, modeled up his plan in SolidWorks, and got to work. It was designed to be a moka style espresso pot sized around both the size of stock he had, and three purchased parts: the gasket, funnel, and filter. The base and top were cut on a combination of lathe and mill. He had some good tips on working with deep thin walled parts. He also used his CNC to cut out some parts, like the lid and handle. The spout was interesting, as it was made by building up a glob of metal using a welder and then shaped afterward.
As usual the video is of [This Old Tony]’s exceptional quality. After quite a lot of work he rinsed out most of the metal chips and WD40, packed it with coffee, and put it on the stove. Success! It wasn’t long before the black stuff was bubbling into the top chamber ready for consumption.
