The router bit looks too aggressive to work with small pieces of wood IMHO.I guess I'm not understanding the problems folks are foreseeing trying to cut guides with this cutter. They put fences on router tables for a reason.
I've been turning the wedge bar down, and am not having a lot of luck. The comb usually gets drawn off center, well to one side and sticking from under the top bar by quite a bit. I'd love to try a more pronounced wedge like this router bit is producing.That would look good alright, but seriously I've yet to try a comb guide that they wouldn't work with. Popsicle sticks, paint paddles, chamfer strip, or just turning the wedge bar down - all work fine - it just doesn't seem to matter. No need to wax them or anything.
Maybe my bees just aren't picky, but I think I could tape a ball point pen to the top bar and they would draw comb from it. I should try that.
