Too much character for reflex/recurve?
« on: April 26, 2021, 11:39:10 am »
Is there "too much character" in a bow for it to take reflexed tips? I am working on an HHB bow that has a large knot and a crook on the same limb. I don't have a good picture of it right now but am wondering if reflex will put too much stress on a weirdly shaped limb?

If you do your part tillering there shouldn't be any problem with the knot and crook.

Depends if you are willing to risk all your work going BANG!
It's as simple as that.

Thanks guys, I have the bow out to 10" at 55lbs so I have a lot of work to do before I reflex it. Del, I am definitely a little worried about that! But I am looking for a mild reflex in the tip for that little extra zip and a smoother draw. I'll probably risk it if the bow has been holding up fine when I get it pulled farther.

I generally have found that most anything I’ve done to a bow limb that has extra character runs a risk of creating a compromise.  What I would have to check would be how the limb will be stressed when drawn.  By that I mean, what vector plane(s) will be stressed on the wonky limb during the draw.  If there’s going to be a lot of torsion type stress that would make me nervous.  ...but if the limbs will move in a single plane as the bow is drawn it’s not as concerning.

If some propeller twist was taken out and the bow seemed to be bending along a single plane, that should help then?

If the stave has quite a bit of character then it's best not to introduce a substantial amount of reflex of recurve....keep it mild

Yes you've got to realize that character bows are always a compromise. They carry more limb wood to do the same job as clean wood.

Sorry, I don't have a pic of it right now, it's up north where I can work on it. Next time I do work on it I'll snap some more pictures.

Alright, here is my bow I am working on.

HHB
68" ntn
looking for 55-60# @ 30"
2" at fades and tapers down where I thought it could
Bottom limb is the one with a lot of character

Any thoughts on putting general backset in the bow while heat treating the belly or doing a mild reflex in the tips?

Hmm, for me 68“ would be to short for reliable 30“ draw - even with that drawweight…

Yes it is a bit short for a 30" draw. Make it work into the fades a little (fine line stuff but it will help get the drawlength). I wouldn't recurve the tips due to the tips and handle not lining up. It will still make a flatbow though, you could mildly flip the tips but I wouldn't. A heat treat and reflex the whole limb, maybe only an inch or so. Remember fresh low set wood will give you a fast bow. Adding reflex etc makes that goal harder and you can end up chasing your tail. Keep it simple to start with :)
