Hi Guys
Have you thought about having the paddle wheels made on a 3D printer?
I have just two paddles made they are 85mm. x 20mm and were made in one piece for my Great Eastern 1-200 scale working model. At first a friend did make them on a 3Dprinter for free! they were in sections, spoke,rings and blades that I had to glue together but the spokes would not line up so I had them remade commercially
cost $20.00 for the cad drawing $65.00 for the wheels here in Adelaide,
cheers,
Hutch.
