While the idea of wooden wheels doesn't particularly bother me, I don't find the look of flat wooden discs particularly appealing.
One of the reasons I opted to cut the wheels out of solid pieces of hardwood - rather than plywood - was that I was thinking it might be nice to have the option of trying to make the wheels look a little more like metal wheels by giving them some depth and shape.
I found this picture on the web, and I liked the old-timey look to the curved spokes:
Then I made a stencil out of it in Photoshop:
I made one each for the idler and spool wheels, plus another idler wheel version to see which I liked best. (I ultimately decided that they'd both have the same curvy spoke pattern):
I then got the spray glue, the FrogTape and applied the stencil to the wheel like I did with the pressure box window, then took it out to the scrollsaw:
I also rounded the spokes a little using a dremel tool with a sanding spool end, and then kept smoothing with 220 sandpaper and some needle files. (I haven't yet drilled out the full 1/4" of the center hole, but I'll do that when I go to mount it on the shaft).:
I think I'll use some "hammered finish" paint on them once they're both sanded and primed. I just can't decide between a black/dark grey hammered paint color, or a gold/brass hammered finish...
