Here are a few pictures from the toy crane I finished for my son.
The crane has a two piece hub that the rope winds up on. The inner hub is not visible and is connected to the steel rod that passes through it’s center. The outer hub is what the rope winds up on. Each hub has 4 1/2” diameter rare earth magnets that line up with each other. If too much weight is put on the rope then the magnets slip and the outer hub spins. With the twist of a screw driver the two piece hub can be made to act like a solid one piece hub. It is constructed mainly out of baltic birch with parts from several online sources.
It is very sturdy and strong enough for an adult to ride on as well. He has played with it a lot and has not once come close to tipping it over thanks to the wide base. The neighbor kids love it as well.
