Here my final project at school. I had to create a machine that could sharpen all kind of spikes: rounds, squares, rectangles.

I had to make it also, but it wasn't a success... Teachers decided I couldn't use any CNC, so I didn't managed to get a few parts done with the right tolerances. result, the gears weren't on their pitch diameter...

The concept could be great. Some people told me to continue and make it better, but I have other projects in mind!
