Wouldn’t it be great if you could mark stuff with your name, slogan or logo in a way that wouldn’t wear of? You need a branding iron! But instead of ordering really expensive ones, you should consider making your own. As this tutorial from John Heisz shows, it isn’t tricky at all. With just an old metal wrench as material and simple tools like drills, files, a hacksaw and an angle grinder, John Heisz makes his own branding iron with the name of his website “I build it.ca” with excellent results! Just watch and learn how you could make your own permanent stamp. And if you need help doing the pattern transfer, check out our How to transfer inkjet prints to wood post, it works on almost any surfaces.
Most electrical motors uses electromagnetism in order to transform electricity into mechanical work, but there’s another type of motor, the electrostatic motor, that works differently. Instead of using magnetism, electrostatic motors uses high voltage to attract and repel parts of the motor, causing them to turn. There are many ways of making such motors, but most tend to have very low strength and torque. There are the exception to this rule though, and in these videos from RimstarOrg one such exception is studied in detail. It is called the “Corona motor” and apart from being cheap to build, it also have high enough strength and torque to be a viable motor for practical applications! The downside is that it needs very high voltages, and if you try this build, be extremely careful not to get a shock! And if all possible, avoid using high voltage transformers that plug into the wall socket. They can kill. We are not kidding.
In this video, Will from Tested.com follows Adam Savage ( Mythbusters ) as he make a new quick access holder for his multi-tool. We like Adam, because even though he makes really specific things, he takes the time to teach general tips and tricks as he goes along. This video is just such a tutorial, and even if you do not want a multi-tool holder, watching this will teach you a lot about the process of scribing, cutting and folding metal sheets. In this case the metal is aluminium, but the techniques he demonstrates here is the same for any metal sheet, except for the use of a chisel as a metal bending tool. Not mentioned in this video is how to remove the layout fluid after the piece is done, but almost any solvent will do, even nail polish remover. Adam will also, unwittingly, teach you the value of thinking things through before taking actions 🙂
This is an absolutely excellent tutorial on how to make carbon fiber pieces for cheap! Did you think making carbon fiber parts was messy, expensive and complicated? Well, unless you’re doing some curved shapes, you’re wrong! For most applications, there are pre-made carbon fiber products, such as carbon fiber planes, carbon fiber profiles, even carbon fiber parts that you can buy for a couple of bucks and change yourself with ordinary cheap tools. If you have a hacksaw, you can cut carbon fiber products! Just make sure you follow the safety advice in this video because even though carbon fiber products aren’t toxic, it can cause you a lot of irritations if you do not use proper safety.
