Every idea has to start somewhere. Anytime I start a new project, I draw sketches with a .5 mm graphite mechanical pencil and here are some of my early sketches that go back years on this project. I love these sketches because you can see the eraser marks on many of the drawings. When I look at something, I can vision what it looks like from the inside out. While most people invent things from the outside and try to figure out how it works in the inside, I figure out how things work on the inside and invent things that work in my mind before they even touch the drawing board.
