Title: Bow design for a thumb-ring shooter
Post by: Stickhead on November 25, 2020, 12:35:18 pm
Hey, all,
I知 going to build a bow for a novice archer friend.  He makes knives, so we池e going to horse trade. The thing is, he痴 missing his middle and ring fingers on his drawing hand, due to a shotgun attack years ago.  Therefore, I知 thinking a thumb ring would be perfect for him, right?

I知 thinking of making him a flip-tipped pyramid self bow, around 45#.  I致e never used a thumb ring, so I知 wondering:

1) Does shooting with a ring affect his draw length?
2) Are there any design considerations I should take into account (limb lengths, positive tiller, overall bow length, stiff vs. bendy, etc.)?

Thanks for any advice.
...Tom

A thumb draw increases draw length, all else equal.   Make the arrow pass narrow.  I wouldn't worry about much else.

Normally drawlength is higher, as anchoring is not corner of mouth ...
I think every design (maybe besides ELB) is possible, but would suggest a shorter bow. String angle at drawhand is not the problem with a thumb ring.

Can he comfortably draw, hold and shoot a 45# bow? That's a lot of weight for a new archer, regardless of how big or tough he is.

I think so, but I値l have him try one from my wall before finishing his.

Left hand bow for a right hand shooter and right hand bow for a left hand shooter.  :OK

I値l second the question about draw weight, remember thumb draw focuses most of that weight onto one finger so starting lower and working up might be the way to go

Oh, right!  I missed that.  Maybe I should try to make an ambidextrous one to give him options.

Or.... I suppose he could use a release.  Anybody have an opinion on that?

Clay hayes has a recent video about thumb release and paradox on youtube. As far as a thumb ring goes that's pretty ancient I'd call it primitive
