Summary

a little "roller coaster" that is powered by a windmill

note: the last picture shows how all the parts go together, but it was taken before the windmill blade and the ride base where changed.

Instructions

i designed this on 123D, it is easy to put together all you have to do is put the windmill shaft through the hole on top of the windmill base. the put the windmill pulley on the shaft, next put the blade shaft through the small hole on the top of the windmill base then put the blade on that shaft. that completes the windmill, now you need to construct the ride. first insert the ride shaft into the top of the ride base, then put the pulley on that shaft, attach the car and arm to the small hole on the top of the shaft and press the car into the groove on the outside of the base. the last thing to do is to add a rubber band of some type of string between the 2 pulleys.
