How I built a gas-powered vacuum cleaner for use in gold prospecting
It was easy. You can do it too
One of my many hobbies is recreational gold prospecting. I've been gold panning on my vacations for many years. It's a lot of fun. It's great exercise. I get to do it in really scenic locations. I have even found some gold. Gold likes to collect in cracks and crevasses and really hard to get at nooks and crannies. What is really needed to clean out those pesky cracks and crevasses is a vacuum cleaner. Problem is, where do you plug it in out in the wilderness? Solution, replace the electric motor with a gasoline engine. Now you have a vacuum cleaner that will work anywhere
