My Wife wanted a wooden wheel barrow for a decoration. Building the wheel was a challenge but came out pretty good I think. She liked the bare wood for the wheel so I sealed it and left it bare.
I'm really bad about making something but never taking pictures. I apologize for not having more detail about the wheel but maybe you can see how I did some of it at least. It was made out of scrap 2x4's (that's why so many holes) in two halves with the spoke holes drilled out before glue-up. I clamped the section halves together, drilled the holes at the joint (1/2 spoke hole in each section), assembled the center assembly then glued each "half wheel" together with the spokes. Not very clear but maybe you can get the idea.
