The only thing better than making a cool project is making a cool project that helps make more projects! Case in point, [Greg Stephens] and [Alex] wanted to colorize steel bearings for use in a Newton’s Cradle desk toy. After trying out a torch and not liking it, [Greg] and [Alex] decided to build custom aluminum vise to hold the sphere while it sits in the magnetic induction forge.
Their vise–they call it the Maker’s Vise0–isn’t just a one-off project to help make the cradle. [Alex] and [Greg] aspire to create a tool useable for a wide variety of projects. They wanted it to be oil-less and it had to be customizable. Ideally it would also have an acceptable grip strength, be easy to use, and look good on the bench.
[Greg] and [Alex] have set up a Hackaday.io project, and their logs show a lot of progress with two finished iterations of the vise and a variety of 3D-printed and cast parts to go with. Recently they brought in a 2,000-lb. load test and tested it on their vise collection, including the two prototypes. Version one rated at 500 lbs. reasonable clamping pressure–meaning they didn’t exert themselves to max out the pressure. Version two sits at 800 lbs., still nothing like a desk vise but far stronger than a Panavise, for instance.
Their magnetic induction forge project was also a success, with the team able to quickly change the color of a steel ball. Check out a video after the break…
