Very nice bow. Once you get the hang of the way to form the d profile, and then tiller it, it gets like second nature. Just like making a flatbow but different. You get the little processes of it stuck in your head. I am sure you will master it, regarding the skillful bows you have posted and post on here all the time. I am still getting the hang of making d profile bows myself, but it's getting easier and easier, I just take the unworked stave, mark the 3 main alignment points, and rough it out real fat and chunky with a hatchet to remove most the excess wood. And then erase the two marks at each tip, so I can use my eye, by looking down the stave, to do the rest of the roughing out, (I go from hatchet to butcher knife, the butcher knife is what I substitute for where everyone else would be using a drawknife). I make it a square, just a bit more wood then I would need. And then lastly I work it down and round the belly/shape the tips, exc, with a farrier's rasp. I also round the edge's on the back just a bit. Then I floor tiller it by removing wood from the belly, and sides a bit. But mostly the bottom of the belly, as taking wood off the sides does not effect tiller as much. This part and tillering in general I do not find too much different than tillering a flatbow. Once the bow is floor tillered to where it I feel it is ready to put on the tiller to tree to see what it really looks like, I will cut temporary nocks in it. After it is tiller fully, I actually go and sand to as much as I am going to sand to, usually 600, (which can always effect tiller a bit sometimes anyway), and also burnish the whole bow, and then I will measure and put the horn nocks on. I do this because I hate accidentally scratching the polished nocks with sand paper.
