On the shortlist of dream tools for most metalworkers is a waterjet cutter, a CNC tool that uses insanely high-pressure water mixed with abrasive grit to blast sheet metal into intricate shapes. On exactly nobody’s list is this attachment that turns a waterjet cutter into a lathe, and with good …read more

[Ivan Miranda] is always experimenting with 3D printing, and recently has been taking his work on the water. His latest creation is a racing paddle boat, but its performance left [Ivan] with a need for speed. Cue the development of the 3D printed water jet engine (YouTube link, embedded below). …read more
When [Ben Krasnow] sees an interesting phenomenon he pursues it with a true scientist’s mentality, though it doesn’t hurt that he also has the skills and the workshop. This time he’s produced a glowing plasma by impacting fused quartz and other materials with a high-speed water jet.
The jet of pure water emerges from a 0.004″, or 100 micron, diameter sapphire orifice with a flow rate of around 2 milliliters per second giving a speed of 240 meters per second. It collides at 90° with a dielectric material where the plasma is produced as a toroid surrounding the collision point. …read more
The iPhone 8 was just released last week, and that means some people were standing in line in front of an Apple store for hours waiting to get their hands on the latest and greatest glowing rectangle. [Patrick Adair] had a better idea: he would stand in front of an Apple store for four hours, then do something productive with his new smartphone. With the help of a waterjet, some resin, a lathe, and some very fine grades of sandpaper, he created the Apple Ring.
Setting aside the whole process of actually acquiring an iPhone 8 on launch day, the …read more
Most hobbyists don’t have waterjets in their garage, but they would if they could! A Waterjet (or Water Jet Cutter) is a marvelous tool. Simply mount a high-pressure stream of grit and water on an x-y gantry, and the pressure generates enough erosion to cut through just about any thin material. Unfortunately, claiming your own waterjet will erode away a nice big hole in your pocketbook too. Machines up to this point start at about $75K, not to mention that they’d claim the better part of your workspace in a two-car garage.
Most of us everyday hackers that want to …read more
