Getting to full draw without losing thickness or gaining set?
Aksel:
May I ask which bow you´re copying?
RyanY:
Dave, I think the issue is that changing the design parameters doesn’t change the properties of the wood including how far it can compress or stretch. While I can’t discount your anecdotal experience, it doesn’t make sense with what we know about bending physics and doesn’t match my experience.

ok maybe if it was longer......... or osage.....
but comparing apples to apples, or in the case of the bow being discussed, hoping to maintain thickness while bending further without taking additional set is unrealistic
that said, stuck needs to decide if the bow needs to be a replica with exact limb thickness dimensions or a shooter, which tillering without set, calls for slightly thinner limb.
If going for a shooter, the reduction in thickness is not all that much
stuckinthemud:
So much of this game is psychological. I cleaned up the side profiles and lost a couple of mm width but then I rolled over the corners which will also have removed a fraction off back and belly along the length of the bow. The extra step seemed to reset me as well so had a productive hour or two without adding to the set, though I also didn’t add to the draw length either…

Ryan. That’s fair. I’m not trying to convince anyone or suggesting that my thinking on this is the only way or right way to go about it. My findings may indeed be filled with many other factors that have contributed to what I’ve seen too. I did not conduct any scientific studies or controlled studies on this finding or opinion and I merely mentioned it reluctantly here as a consideration for stuck. I was aware it may go against the grain. Agree to disagree may be the way to end this debate for now until I can have some solid tests to satisfactorily prove my opinion. I’m open to new ideas especially when it comes to making bows. I acknowledge that I may be wrong on this point according to the current data out there available to us as well as the experience of others. I’m open to that. I’m ready and willing to absorb new information and ideas about building bows. That’s the fun of it. Some things we thought were constants and fixed may not be so fixed tomorrow or in the days ahead. I meant no harm by giving my opinion and hope none is offended. Cheers.
