Any Mechanical Engineers out there? Has anyone developed a pully system for hanging the yak from the roof of the carport? And, if so, would be willing to supply the details. I want to lift the yak up out of the way and don't particulary wish to pay an outrageous price for something commercial. Would try to figure it out myself; however, is someone has already done it - Why reinvent the wheel? Ok, so I'm cheap!
