Heat treating boo backed bow

<< < (3/5) > >>

Will B:
That is looking great Kidder!  Should be a very durable bow with that combination. Good luck the rest of the way. Looking forward to seeing the finished bow.

I bet this will be one of your fastest bows.  You’ll be impressed with results.  My fastest bows often have some heat treatment on hickory or hhb.  I’m excited to see your results on this bow. 

Kidder:
So I thought I’d share my follow up experiences for the good of the group. I made a few mistakes tillering on the long string and when I braced it I had far too stiff of outers and ended up almost immediately fretting the bow. Worked those hinges away but by the time it was done I had very very tiny frets for around half of each limb, maybe more. There are a few places without and a few with more but overall there are tons of tiny ones spread out. I haven’t shot it yet but interestingly it has about 2 inches of reflex still. I will shoot it in and tweak the tiller but it’ll go into the “meh” bow pile. Most of the heat treat is gone. I suspect part of the problem was design - I was only 1.3” wide from fades to the last 12 inches. I’d have liked to have gone wider but that was all the width I had to start and wider also means thicker when dealing with boo so it was a trade off. I should have also gone thinner before the heat treat on the belly so as to maintain more at completion. But not sure that would have solved the issue as it still fretted in places with some toasting left on. Not saying Hickory Boo bows are impossible but they aren’t easy and I haven’t succeeded yet. As my kids would say, I definitely had the “cheese touch” on this one - everything I touch turned to cheese!

Ah man sorry to hear that it didn’t meet your expectations.  I had high hopes for this one myself.  I’m surprised at that many frets.  The neutral plane too far one way I suspect.  Who knows maybe just a bad section of hickory?   I would think that the boo backed hardened heat treated hickory would be a winner for sure.  I wonder if too much of hardened cells were removed like you say.  Hard to know exactly at this point.  I’d be interested in looking into this further with you when I get back.  I gotta think something went wrong there.  I reach out when I get home.   Cheers. 

Stickhead:
My only experience with boo-backed hickory was a disappointment, too.  The boo was too thick, and I had to remove practically all of the hickory to get it tillered.  Ended up with a lot of set.
