I think I've got it as good as I can get it, and have started to finish it off. It seems like it gained a little power since I got the first sealer coats on -- I don't know why, except when I had tried weighting and shooting earlier after heat treating it was so wet out that maybe the humidity got right into the bare wood. It was drizzling at the time. I dunno. Just seems to have more punch now and be harder to draw. And it still has that surprising shooting consistency in my beginner hands.
I have to admit that the tiller isn't textbook perfect: the shorter snakey lower limb bends more than the upper does. But I don't want to lose draw weight to try to even it up, and I'm super happy with how it shoots and feels. So I'm just going to say, it was as good as I could get at my stage (and ability to judge things). I have 3 more elm staves to improve my skills on.
I'll get more pics when it is finished, braced and drawn, but here it is just raw -- no handle wrap or arrow pass. Well kinda tempted not to put a wrap on. I like the wood shape so much. Even though I already prepared elm bark for it. Hard to decide.
