Looks pretty even to me, Ruddy - so far, so good. Every time I got nervous I leaned more toward either scraping with a stout knife (Kbar, etc.) or back of a piece of industrial hacksaw blade (I think I have a couple extra of those pieces - I'll check), or sandpaper. Nothing wrong with that, IMO, to keep your nerves in check. However, don't let it bulldoze you. Though no one wants to lose one (stave/bow), especially at this stage (when things are looking so good), it is still just a piece of wood you are turning into a bow. It is not your boss - make it your partner if you can but stay in control. Just like you do on the cabinets you build. Keep on keepin' on, buddy!
