As a gear-head, if you’ve never seen a custom wheel made on a cnc machine then you’re truly missing out. First a big block of aluminum is placed on the jig, then the design program is entered defining the shape and all its intricacies, then you hit the go button and watch your vision materialize in front of you. It’s actually not that simple but you get the idea. Here we have a motorcycle helmet being constructed and the process is amazing. Seriously, this is some cool stuff.
