RE: brace height, riser or ATA
Arthur, Gibblet-
The person who wrote the article has been building high quality compound bows for over 30 years. While it is quitepossible that the wording may not bepalatable to everyone, the context howeveris very sound. Take any bow-- deflex, reflex, straight,or whatever,and draw a triangle from the pivot point of the grip, up to the pivot point on the outer radius of the cams where they meet the string at full draw, and out to the nocking point at full draw. Everything forward of the angle itself (riser)has no bearing on the forgiveness of the design, it could be shaped like a banana and it wouldn't matter as long as the brace heights were the same. Also the mechanical advantage ismute as everything forward of the triangle itself is a rigid beamwith the limbs bent at full draw and the only hinge is at the cam/string connection. Cams themselvesplay a largefactoras far astorque goesas well and this may be where some may be pulling their theories from due to differing designs for different bows and their individualriser design. When oneuses thetriangle howeverit is easy to see what affects theforgivenessof any bow.
