I have coming a Dryad 13" ILF Eplc riser , Border. HEX 6S long 30# on 25" riser , Dayad Legend ILF ACS 44# mediums on 19" riser .I figured Dryad ILF riser
and Border limbs = 58" bow 42# @ 28", Dayad Legend limbs = 48# @ 28" ,56" bow .Can anyone help with brace hight and or string length ? Thank You Rick
Your number should be in the ball park, though with the Border limbs you may end up a couple pounds lighter than you calculated possibly. Reason being the pad angle formula that Dryad uses on their risers, I think they try not to go more than 8-9# over what's marked for a 25" riser. But don't worry, those Hex limbs are so fast and efficient they will be plenty powerful for any deer using a sharp broadhead. BH wise I would try 6.5-7.5" as a range to try and see how the setups shoot. String wise you could prolly do a 53" actual string length for the Dryad setup and 55- 55.5" string on the Border combo and be good. Remember with ILF and all the different manufacturers there are 'rules of thumb' but no actual industry standard so I would get yourself a pull scale and measuring tape to help adjust the limbs to get exactly what poundage you want. The primary function of ILF is not to have a multi-weight bow but to set YOUR draw length, I.e. the stack point of any given set of limbs custom to your draw. Have fun!
It is not always cut and dry on poundage on an ILF,you can have limb pad angle on risers that can effect to end draw weight.I have a 17" riser and it added more then 1# for 1" on the weight marked for a 25" riser.It should have added around 7# on the limbs but added 14# due to limb pad angle.When I make a string for any bow I get I'll measure the actual nock to nock length and then make a string 3" for recurve or longbow.With a short riser I would start around 7.5" and go up or down from there.
A good start point is before the string is just coming out of the bottom of the groove on the limb. I find that if I lower the brace to the point that the string is laying against the flat of the limb I get more noise and limb vibration.
No hard and fast rule. Depends upon you and what/how you shoot.
