I recently installed a winch in my hangar to pull the plane up the hill and into the hangar (to save my back and my wallet). I have been connecting the winch cable to the tail tiedown ring but I notice that the ring is bending under the strain. This is the Van's forged ring that they sell on the web site. My question is whether this is a problem with the ring (soft material) or whether using this as a tow point is a bad idea and may overstress the attached structure. Anyone else have this issue?
