I bought a cheap 1000 lb winch and attached it to the wall between the studs (in the garage). I ran the steel cable up to a pulley I suspended from a length of 2X12 that I placed above the rafters to span 5 of them, spreading the load. The pulley was just one I selected on a trip to the hardware store. Take a look at the ones there and pick what looks like a good, strong one. Mine will support 1000 lbs and MOST of my deer don't weigh more than that!
