Nitro Engine PENCIL Sharpener!

My friend found a Nitro RC car in the garbage. I decided to turn it into a high performance pencil sharpener!

The first step was to get the engine running. When I got it the piston was seized and the carburetor was clogged. I took everything apart and cleaned it before putting it back together.

Once the engine was running I could get to work attaching it to a hand crank pencil sharpener. I decided to utilize as much of the RC car as possible. I welded the universal joint from the RC driveshaft to the hand crank of the pencil sharpener. Then I cut it off and rounded the edges with a grinder.

I did a test run and the pencil sharpener seized. It seems the cutting wheel isn't designed to spin at 30,000 RPM :)

I used a shock absorber from the car to "engage" the brake at all times. This way the pencil sharpener isn't spinning until I want it to. This reduces wear on the bearings/bushings.

I added some modified bumpers and guards from the car to make the device look more complex and cool. It keeps my fingers out of the gears too!

To my surprise the thing actually works! And it didn't fall apart after it's first use. Everything is still in tact and working.
