How often did you get yourself stuck and said "damn, I'd give an arm and a leg for a winch". Worry no more, help is on its way. Here's a How To video about how to make your own winch.
I first discovered this ingenious flip-flop winch from a YouTube demonstration by Mors Kochanski, the Godfather of bushcraft. A search of flip-flop winches on YT will garner several clips demonstrating the power of using two logs and some rope. So why would I add my video to mix? Because it's only theory until you put it into action by Doing the Stuff!
