Quick dirty arrow cresting machine

My quick dirty arrow cresting machine. I still have to find a better arrow s nock junction to the motor (to get less vibration) but I was able to build this from parts in less than 3 hours and it also performs as an arrow spine tester when I rotate inwards the two middle wheels. I will use paint and not markers to get a better finish and I will use a design based on my family (Múzquiz) coat of arms.
