Your Ship's Wheel
Many people are opting for "Destroyer" style wheels. One recommended source was Fisheries Supply. This looks like the kind of thing that would be best to be bought, unless you have the metal working skills and equipment.
On the other hand, some people want the more "shippy" looking wooden wheel. These can be purchased (also from Fisheries Supply among others), but run $350-1,350 just as an example.
So, it gets tossed out that if you can build a boat, surely you can build a wooden wheel... well, there are even plans and instructions available for free... get cracking!
One piece of trivia... the "index grip" or "king spoke" is the "peg" that extends outside the wheel and points straight up when the rudder is centered.

Thanks, neat idea
Thanks for pointing out another neat way to build a wheel... hadn't thought of having a bandsaw blade welded together inside the loop, slick.
Router sounds about like my speed. A CNC machine would be perfect if you have access.
