Sugar Maple D Longbow
Robert Pougnier:
Thank you! No wrapping, it's just left a little thicker right at the bend.
Just did some more shooting with it this morning and it's definitely an easy sweet shot! No increase in string follow as of yet.

@willie I used the elliptical profile on p.274 of TBB vol1 as a guide for the tiller profile. Last D bow was too bendy at the handle section and I spot treated it that way. I was more careful this time around and like the tiller better. There is some near handle character that throws off the tiller picture just a little.

Did your spot treating help? Its an interesting method for tillering and I hope you can share more about the pro, cons and results.
just how much to keep the handle stiffer was an interesting discussion a while back, at least when it was about warbows.

Nice ELB, Robert. :OK

@Willie
So that's an interesting question. In my impatience to get to work again I flexed the last D bow while it was too dry (just 18 hours after heat treating the handle/fades) and it developed a compression crack right at the fades. That was three weeks ago. I've now sinew backed it in hopes of moving the center of balance slightly away from the belly. It's been two weeks since that and it's since taken a half inch of reflex and I'm almost ready to do a patch over the belly. I'm going to put a string back on it in 2 more weeks and see how it goes. I was pretty bummed to get a crack, it seems like the vast majority of mistakes I make are from rushing processes and wait times that are pretty important! The last D bow is a fair bit shorter though, 60" ntn, and I plan on tillering it to 40# at 27" once the sinew is cured. I'm hoping it survives into a decent shooter.
The method itself though, spot heat treating, seems to work and be pretty versatile. I've corrected tiller a couple times with it successfully and I think it's a great tool.

Thanks Everyone!
