Most posts get none or maybe one comment, but the post on 12 spoke wheels got a few people interested.

Besides the trouble to manufacture, to me, they don't cut it. The center hub where the spokes connect is very narrow making the two side's spokes almost inline which defeats the dimensional look of the originals. Instead it produces a less interesting wagon/stage coach wheel effect. From the Joyrides Art Co. blog.
