Thanks for this video. I am working a maple board longbow and having slight twist in one of the limbs as I am at full tiller now. Love your work and thank you for all your great instruction.
I sure wish the YOUtue algorithm showed me your video 6 months ago THANK YOU for this answer I learned how to fix limb twist the hard way. Another bow for the bonfire LOL
Ok... first, you need to enter this process with the mindset that the bow is already in a condition that will relegate it to the rack - never to be shot or relied upon in the future. This understanding will grant you the freedom to do some pretty extreme things without fear of making it a bow that will be relegated to the rack - never to be shot or relied upon in the future. That having been said, I would start small and work my way up until it behaves. First, if the twist is mild, you can deepen the string nock on the offending side to try and bring the string back into alignment. If that works, then you can just taper the limb tip until the nock groove matches the others and you're done. If that doesn't do the trick, then I would, with the bow unstrung, take the twisted limb and put a clamp on the tip such that the weight of the clamp pulls against the twist. Then clamp the grip into a bench vice and hang some weight from the clamp at the tip forcing the limb into a significant twist opposite of the offending twist. Let it sit in this condition for several hours and then measure results. Use progressively more counter twist and length of time to get desired results... If that doesn't take care of the problem, follow the process above, but once it is under enough strain to pull the bow into a twist equal to about one and a half times the offending twist I would then apply mild heat to the limb where you suspect the twist is occurring. repeat this step with progressively greater counter twist, heat and duration until the twist is cured. You have to be very careful here as heat can compromise so many construction elements that you could be slowing ruining the bow - but it helps to remember that it was essentially already ruined before you started... Good luck!!!
Thank you very much for your video. I just discovered your channel. My knowledge about archery is null. I have a longbow with a twisted limb, and I want to know if heat or water steam debilitates permanently your limbs.
There‘s a little more qualification that I would need before I can answer your question. Most importantly, It depends on the material makeup of the bow itself. A self-wood bow would offer no real issues, but a composite bow (laminated natural materials or otherwise) would need special consideration. Another important distinction is that heat and steam are functionally the same - it’s the process of heating the wood to the point of plasticizing (ability to permanently bend without breaking). As for debilitation of the limbs, heating will collapse some cell structure of the wood which obviously results in a bit of weakening (making the wood more brittle) in the areas that are heated - that is why this technique is primarily utilized at the grip and/or the tips where bending and leverage are at a minimum vs the working limb. My only other concern would be delamination of any glued surfaces in the case of a composite limb.
Any thoughts on how to avoid limb twist in the first place? I'm making a bamboo/ipe R/D bow for the first time and both limbs look like they have Peyronie's disease. Not sure what I did wrong other than too much reflex too close to the center of the bow.
I’m wondering if you tillered all of your parts in advance of the glue-up… Generally speaking, any limb twist in pre-tillered components is pretty minor and can be easily corrected.
@@meadowlarkadventuregear I did pre-tiller, and not a lot so far after glue-up. It's pretty much a straight sideways bend. Thinking about it closer, it's possible I did it by sanding unevenly on the belt sander. I did rush through that part after the glue-up. Luckily I bought a bunch of ipe and a 50-pack of bamboo. Again, thanks for all the great videos.

Thanks for your tips and tricks! I need to straighten my ELB which tips are already quite thin.
Thanks for watching! Hope the advice helps!
I’m looking to fix the twist on a limb of a Fred bear bow Grizzly that I bought used. Any recommendations for finished bows?

@@meadowlarkadventuregear Thank you for your response. It is an all wood bow. It has a twisted limb.
Very helpful information. Thank you
Glad it was helpful!
