Introduction: Nitro Engine PENCIL Sharpener!
Runner Up in the
My friend found a Nitro RC car in the garbage. I decided to turn it into a high performance pencil sharpener!
Step 1: Get the Engine Running.
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.
Step 2: Adapt Engine to Pencil Sharpener.
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.
Step 3: Connected Drive Shaft.
Step 4: Test Run.
I did a test run and the pencil sharpener seized. It seems the cutting wheel isn't designed to spin at 30,000 RPM :)
Step 5: Add a Brake.
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.
Step 6: Make It Look Cool.
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!
Step 7: Finished!
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.
We have a be nice policy.
Please be positive and constructive.
