Good looking bow. When I first studied it I didn't even notice that it was bending more in the fade on the right. What caught my eye was the stiff mid/outer limb that is causing the potential excess belly crushing too near the fades. I agree with everyone else that you could probably stop right now and have a shootable bow. I just think there is also the possibility that you could say that it gives you a chance to take your skill to another level, if you haven't already
What if you lighten up that outer 2/3 and heat treat the whole thing? The more the stiffer otter doesn't do its work the quicker that bow will not be fun to shoot anymore. why not tiller it down a little more and restore some of your lost poundage in the tiller by heat treating and maybe even piking an inch or two. Besides some of the reason for the set can be moisture content. I don't know if your in a non dry place but hickory loves the desert and low hunidity. Around these parts hickory is moisture finicky and can change with the humidity. I would think heat treatin it would reduce some of your set if you heat it and clamp it into a little reflex to cool. I t might be worth a try. I did it with a hickory pyramid last year that I made for my dad and it improved it noticeably.
I think that the way we learn is to continue to go deeper. But thats just me. I think your almost there on that bow, just a few corrections and it will be a durable shooter longer term I think. What is the current poundage?
