Hi there, I just wanted to interact a little more with the community and I thought I would start by sharing my Lego model I designed and built based on my favorite carnival ride; The Tilt-A-Whirl. However, my model doesn't tilt, and the cars don't spin freely, they are connected to a gearing system so they are always turning while the ride is in motion.
The first design could only be operated by hand (and shot on a really crappy camera)
I then added a Lego motor, and after a bit of trial-and-error on how to attach it, found that using a worm gear to drive the entire platform was ideal.
Finally, I submitted it to Lego for consideration to become a real model:

I hope that you like it and let me know what you think.
