I made the ring. You could buy a strong eye bolt though. It bolts through a steel beam that straddles a couple of roof joists. I have used it when working on a quad too.That's a very good idea. Tilting the sled on its side in this way is probably only putting a 2-300 lbs of weight on the beam since the bulk of the weight is in the front and you've always got a ski planted on the ground. Where did you get the ring? The cable hoist is just a manual, mechanical advantage type of deal?
