Build Your Own Motorized Ozone Killer

Here are detailed instructions from Canadian YouTube user Davidsfarm, a “self employed garbage picker, problem solver and repairman” on how to build your own motorized scooter from a two-stroke weed eater motor (with a clutch) and bicycle found in the trash. You’ll need to know how to work a welder, a hand grinder, and a drill, and maybe a lathe and milling machine. The bulk of the video is a lot of mumbo-jumbo about his creative engineering process, but, check out 9:52 for gear ratio explanation and how fast you can make this sucker run (Ha!) and 11:53 for a demonstration.
