I live in lovely Ol' Seattle. It likes to rain here tons, specially during winter, fall, and spring. When it rains, I like to dink around in the machine shop at my place of employment. I am also an avid hiker and camper, so this project fits right in with my interest. I designed and constructed a fire piston on the lathe at work.A fire piston works like a diesel engine, take air, compress it fast, and Boom. There is no boom, just embers if you use the right fuel.
