Carlo, have a look at the link below and check out the three books on " Making Model --------------" by John Thompson.
Each book will have a chapter on how to make wooden spoked wheels, I use the exact same method, with only a few modifications on how he does it.http://www.wildhorsebooks.com/ModelVehicleBooks.htm
If I have to make a set of heavier type of waggon wheels, then I will use wooden fellie sections to make the wheel, as per what John Thompson describes.
For a lighter type of wheel, then I'll use the 'plexiglass' for the fellies or rim.
Making a lighter type of wheel from wooden fellies is prone to disaster, as the sections do not have any thickness about them, for the glued fellies to hold together, they will and do break apart at the worst possible moment, hence, I now use a one piece plexiglass/sheet acrylic for the job at hand.
When making the fellies from plexiglass/sheet acrylic, the lathe is used to cut them from a small section of the sheet.
It would be nice to be able to get them cut out using CNC, but I don't have one available to use.
'EZnKY' and 'Hauk', the lining is decals, I use CorelDraw to get the design correct and then print them out onto decal paper.
I'm yet to find a 'Leprechaun' down the back garden that can do pin-striping for me.
