The week ahead.

For the week leading up to Christmas, I’ll be machining a full car prototype for the mini coaster. Hopefully using the same method to hold the wheels as before will work with the aluminum frame.

Wheel and frame assembly

The frame will be made from aluminum and the wheel assemblies will be fabricated from Delrin plastic. Just as before, the axles will be secured within internal reliefs. When the two identical parts are mated together using adhesive, two small tapping screws will ensure nothing comes loose.

A video of progress…

In addition to the car prototype, I’ll work to upload a video to see progress and something “festive.”

Either way, just a quick little update for now.
