Limb pad angle has been discussed on different threads, but how exactly does it affect a bows performance, and are any risers made with the ability to adjust that aspect of the connection? If not does anyone make "angle shims" that would allow for such adjustments?

The limb pad angle determines the amount of deflex that is introduced into the side view profile. The more deflex there is on a given length riser the lower the draw weight.

I've shimmed the limb pads on frankenbows several times to get increase draw weight/pre-load on limbs.

Harold Groves gave me the idea years ago.

The more acute the limb pad angle, the more early tension on the string, which usually translates into more performance as well.

Of course, one can adjust the limbs by how one sets the limb bolts to either increase or decrease the angle in relation to the bow's limb pad angles. That adjustability pretty much obviates the need for shims. It accomplishes the same thing.

The shorter the riser, the more reflex in the pad angle. Allows for more draw length before stacking in a short bow. The more reflex, the less limb preload, making the bow slower. That is why it is common to see longer bows actually faster than short bows. I have a 26" draw and have made tapered spacers that fit under the tiller bolts to give more limb preload, but you need to be careful with that.

With a gillo gt riser you can set whatever limb pad angle you want. The whole pocket swivels with limb bolt adjustment. If interested, pm me. My gt riser is a 19", but theyre available from 19-31".

loose and easy, the "typical" ILF 17-19-21" risers will gain or lose AROUND a pound of weight per limb bolt turn in or out, resulting in AROUND 3-4 pounds of adjustement from lightly snugged bolts to bolts out 4 turns. any more "out" thaan this can sometimes get the ILF fitting to "bind" in the riser channel, as it leans, as the angles change. DAS will adjust bit more than ILF, generally, as the DAS bushing does not have sharp corners/edges in a sharp edged channel. Not recommending it - but - on an early bronze Dalaa 17" riser I used to have, I was on phone with a bow tech (Jonhdo) trying to get past stacking with an extra-short set of Sky Conquest limbs on it. We were able to turn bolts out 6 turns, still with plenty of bolts in riser to secure grub screws, and we got past the stacking. Big gap was unsightly, but it (the exercise) helped prove a point. The limb bolts do effectively change limb pad angles, as it were.
