Motor test bench talks the torque

Posted on by

Salvaging a beefy motor is one life’s greatest pleasures for a hacker, but, when it comes to using it in a new project, the lack of specs and documentation can be frustrating. [The Post Apocalyptic Inventor] has a seemingly endless stockpile of scavenged motors, and decided to do something about the problem.

Once again applying his talent for junk revival, [TPAI] has spent the last year collecting, reverse-engineering and repairing equipment built in the 1970s, to produce a complete electric motor test setup. Parameters such as stall torque, speed under no load, peak power, and more can all easily be …read more

It should probably go without saying that we’ve got nothing against the occasional bout of elaborate troubleshooting and repair, in fact it’s one of the most common things we cover here.

We can’t fault them for that.

But we have to say, we generally don’t see those kind of elaborate repairs for something brand new. Unfortunately, …read more

The Most Utilitarian 3D Print Has the Widest Reach

Posted on by

3D Printing is often heralded as a completely new fabrication method, creating things that simply cannot be manufactured in other ways. While this is true, the widest reaching usefulness of 3D printers isn’t for pushing the limits of fabrication. The real power is in pushing the limits of manufacturing for individuals who need one-off parts.

The proof point is in the story shown above. A missing key on a keyboard could have meant an otherwise fine piece of hardware headed for recycling, but was saved by a single part printed on a desktop 3D printer. Multiply this by the increasing …read more

Repairs You Can Print: Model Coal Car Fix

Posted on by

Model railways are a deep and rewarding hobby, and the mechanisms involved can be both surprisingly intricate and delightful. A great example that may surprise the unfamiliar is that of model train carriages, such as coal cars, that are capable of both receiving and dumping a load at various points on a model layout. This adds realism and, if we’re honest, just plain old fun.

When [Phil]’s father received his Lincoln coal car from eBay, it was unfortunately damaged, and incapable of dumping properly. Instead of throwing it away, a replacement part was developed and 3D printed. The part was …read more
