We truly don’t understand if the world needs it however we’re sure pleased [johnnyq90] took the time to develop one. We’re speaking about a nitro powered rotary tool. based on a Kyosho GX-12 nitro engine, typically utilized in R/C cars, [johnnyq90] machines practically all other parts in his shop to make a truly great ‘Nitro-Dremel’. however success didn’t come at the very first try.
The very first prototype was made utilizing a COX 049 engine however the lack of appropriate lubrication cause damage to the crankshaft. since of this setback, [johnnyq90] swaps it out with a O.S Max 10 Aero engine he had lying around in the shop. That didn’t work out so well as the engine was rather difficult to start. On the third try he lastly chose to utilize the 2.1 cc Kyosho GX-12 engine to power up his 20.000 rpm tool. As noisy as one would expect and, from the videos it seems rather powerful as well as it quickly pierces with an aluminium block, cuts steel like a breeze, as well as breezes with other less demanding feats.
But [johnnyq90] is no complete stranger to nitro engines nor to Hackaday. In the past he built, among other things, a nitro powered cordless drill as well as showed outstanding feats of machining in a micro version of a Tesla turbine. We question what’s next…. a nitro powered tattoo gun perhaps?
In the 20 minute video after the break, we enjoy watching the building of the ‘Nitro-Dremel’, in addition to other parts from two previously failed prototypes:
