About:I've had K'nex as long as i can remember but it wasn't until I was old enough to have a credit card and an eBay account that I started working on much larger scale projects. I've built roller coasters and theme park rides but ball machines are way cooler than all of those and frankly more fun to design and build. Sadly I don't like making instructions very much so there's a lot of blueprints which exist only in my head and in occasional videos. For the past 4 years I've been doing a degree in Mechanical Engineering at the University of Sydney but as of November 2013 I'll have graduated and I intend to mark that month with the premier of Project Concatenate. Some of the stuff in there will knock your socks off believe me. Generally speaking I enjoy building elements rather than lifts or tracks because the golf balls I use really don't want to go up at all and a chain lift is the most effective way of ripping them from their earthly bonds. That said it pretty much completes my bio. Welcome everyone and love K'nex!
