Actually, I see what voigts is talking about as far as "inconsistencies" (just zoom in on the last pic). If I went through all that work and it turned out like it did, I probably be a little bit disappointed. In fact, I probably would have tried to fix them (If I thought I could) before going any further. Not trying to sound like an arse, it's just the perfectionist in me (and if I'm not mistaken, voigts too).

voigts, could you maybe do the scroll work on a full sized (h x w) 1/4" piece and then use 1/2" piece with the proper size hole in it underneath and glue/dowel/screw the 2 pieces together after the scroll work was done?
