limb pad angle

[md126]

does anyone know approximately how much weight is increased for each degree of limb pad angle? for example.. if i go from 20 deg to 15 deg would i increase the draw weight 5, 10, or 15lbs, etc..  is it a constant increase or does the weight increase exponentially??

thanks for any info

I asked the same question of an areospace engineer. He stood in front of me and performed a calculus equation in his head to determine the amount of forward movement of the limb tip. After much debate, he and I summised that if the limb tip goes an additional inch in front of the riser, the draw weight will increase 1" accordingly. If your bow draws 3# per inch, you SHOULD have an equivelent increase in draw weight. The fwd movement of the limb(unstrung) will greatly increase performance, assuming that it isn't already too far fwd(law of diminishing returns). Sorry if I got alittle deep, that last cup of coffee is kicking in!!!

thanks pebowbender!  that sounds about right. i haven't measured how much further the tips were moved forward by the increased angle but it is in the ballpark of what you said. thanks again

if a person wanted to decreas poundage on a take down recurve would it be possible to place a wedge on the riser pad,tilting the limb tips toward the face?

it will work that way i have done it a couple of times.
   you can also make a wedge and reverse it and increase OR decrease the weight, it is best to have 2 sets of wedges because of the limb bolt holes.
