Hi All. To fit the towing ring to my carrousel I used a Plastic type bearing from a rotating flashing beacon.
This came compleat with a round plastic shaft through the middle of the bearing.
I cut a hole in the deck to take the bearing,Then screwing the bracket to the underside of the deck.
The next step was to fit the towing ring I screwed this to the bearing, I then made sure the ring ran free, OK. Next step was to fit the walkway it had to be close to the towing ring, so I fitted a small plastic ring to the round shaft that comes out through the bearing, Then fitted the walkway ring this also gave me a base to biuld my superstructure from. Hope this is some help. see img 6774 Showing upper and lower rings. also img 7585
