What do you do in your spare time when you're working in Antarctica maintaining snowmobiles for the U.S. logistics hub and you do mechanical and fabricating work back at home? Well, you could build something out of some of the junk and discards found at the station, like a snow chopper, maybe?
Bob Sawicki and Toby Weisser did just that using the engine and track from a totaled 1981 Ski Doo, bent pipe, a crowbar, whatever would work and except for a couple of odds and ends that cost a grand total of $10, they built what you see here.
The 2 tanks are old fire extinguishers, one now holds fuel and the other compressed air for the refurbished air horn. They say it does 30 to 35 mph on the snow. The build time of about 120 hours makes up most of the cost.
The machine is in the February 2010 issue of Popular Science with a couple of other home made snow machines, but those cost money to build, this just took ingenuity. I like it.
So, ... what's in your parts bin?
