Okay all... I am dreaming up a new design for a take down recurve bow.
I know that if you put less degree on the limb pad, that you will get more weight. Now, does anyone know what the approx. weight changes are?
Say 21 degrees vs. 19 degrees. Is there a chart? It does not have to be exact but a some way to get my approx.
thanks,
Brad :archer2:
I don't think there is a chart. I do know that more than just weight will change, pre load etc. if you go to far you may run into stability troubles. Don't ask how I know this. I think many of the limb pad angles etc were arrived at after much thought and probably some experimenting. Having said that I wouldn't two degress would make much difference. Only one way to find out for sure.
Over the summer I changed my takedown design by 6 deg on each side and it changes the poundage by about 10# on average.
Okay.. that helped. I changed this handle I am working on by 2 degrees and gained about 4#.
I know Hoyt makes an adjustable take down.. kind of like a compound.. tighten the bolt and more poundage. Was thinking of making a design like that, or with interchangeable limb pads.
I thought about the limb pad to change the angle for designing pourposes and wondered if my pins would still slide into the limbs without binding.
Maybe a small change would work.??
Try it.

You would have to make some modifications so that the limb would be able to rotate in a somewhat cross sectional cone shape around the pins or limb bolt. If you are going to use the "limb pad" you will also have to remember that will increase the weight of the bow a little because it will move the limbs away from the shooter and be somewhat like increasing draw length of the bow. That just got me thinking if you were to have a design similar to black widow take down bows you could have a spacer between the limbs and the riser and that would decrease weight when the spacer was in that way you could have a lighter 3D bow and and hunting bow that is the same bow, or someone could work on moving up in weight and only have one bow. ...
Same thoughts have been running thru my mind as well Terry..
Morris.. good thoughts. That is my overall goal.. would be able to have a bow for having fun, then change out the pads / or tighten the nut and go hunting.
I will look at black widows design a bit closer.. that could work.
