Cordless Drill Uses No Electricity

There are few projects on how to make your own cordless drill, but what sets [Johnnyq90’s] amazing project apart is the fact that his power plant is a nitro engine. Not an easy task of course, but he makes it look easier than it is, and we really enjoyed the construction process.

He uses an RC Kyosho GX12 engine that was previously modified, changing the cooling head with a larger one. The engine drives a gearbox that was taken from another drill. All other parts were hand made. The clutch was carefully machined, and the cooling fan was made in a 3D printer. Other necessary parts were the frame, brass spacers to adjust the engine height and alignment, throttle arm and handle. In the end even the gearbox had to be modified for higher speed. The finished drill sure looks and sounds terrific, and seems to be perfectly capable of doing its job.

As with other mechanical projects from [Johnnyq90], the video has good timing and attention to detail. His channel is definitely worth a visit, specially if you like turbines.

Safely Remove Drill Chuck; Receive Motor, Gearbox, And Clutch

There’s a treasure trove of usefulness inside of an electric drill. [Steven Dufresne], Hackaday writer and the mad scientist behind Rimstar.org, kindly documented how to safely and reliably remove the chuck from a drill motor. You may think this is easy, but once in a while you’ll come across a drill determined to hold onto all its bits. We certainly were entertained by the lengths [Steven] went to in the video below to get a Black and Decker to give up its chuck.

An understanding of how the chuck and gearbox are connected, combined with the right tools and a bit of force, gets you a motor, gears and gearbox, and a clutch. There’s not much left in the drill after that, and you can put some or all of those components to new use — like using them for the drive system of a BB-8 Droid.

Many projects (like this walking scooter)┬ámake use of cordless drills as motor sources. Being able to skip the chuck in order to interface directly to the shaft is useful for those projects where the drill is at least a semi-permanent part of the build. Ask your friends, neighbors, and at work. Cheap cordless drills and screw guns have been around for a long time. It’s usually the batteries that go and many people have the drills lying around and will be happy to part with them knowing you’re going to do something awesome with them.
