Guys I have been playing around with the idea of building an ilf riser for myself. I have no idea where to find info on the math needed to build these things. How long should it be? What limb pocket angle? Ideal locations for the shelf ect. Are there books and or technical manuals available? What about for just building glass bows in general. I see binghams has instructions but, not necessarily books on how to design and build these things.
