I know there is thread around somewhere that talks about the wooden steering wheel spokes being loose but I sure can't find it! Anyhow, the flying bridge wheel on my boat is also loose so I decided to do a little investigation to see how it's constructed with the hopes that would lead me to the best solution to tighten it up. I pulled the wheel from the steering station so I could inspect the bronze hub and then removed one bung from the rim to learn what's under it for a fastener.
What I have learned so far ... (1) the hub certainly appears to be solid one piece; there are no signs of a backing plate or any means to access the inside and (2) the rim is held on with a bronze screw. Whether the bronze screw is really a long bronze bolt that screws into the hub is still unknown as I haven't yet tried very hard to remove the screw head. It's bronze and soft and my gentle try at turning it with a screwdriver only succeeded in slipping in the slot. I've got to get the wheel into my shop so I can secure it in a vice and try a bit brace or impact hammer on it. Stay tuned.
Here are some pics.
