I'm an aerospace pattern maker. My main roll is CNC Programming and Machining , 3 -5 axis machines. On the side I run a small automation company, and a digital sales company. I wanted to get kids interested in manufacturing so I started a company Pinewood CNC (www.pinewoodcnc.com) to keep kids focused on learning manufacturing through pinewood derby races. There I offer digital CAD models that can be manufactured on Chinese 3040 CNC engraving routers. I have many video tutorials to help people get started. I don't get totally crazy with car designs as we are making these out of wood ;)
