I'm looking for some opinions on an idea I have. I just hope you all have a good imagination. If not, I'm going to lose you. Imagine if you will, a riser that's a one-piece, 2/3 arc design, with a fixed pulley/wheel on the bottom of the riser, (where the bottom "limb" is currently located). If you can visualize this in your head, then bear with me. Now, imagine on the top of this riser, a single (huge and powerful) limb, or, maybe even two, side-by-side upper limbs, with a center-shaft mounted cam. (Can you see it?) Would that not alleviate the headache of timing two cams/wheels? Would it not also alleviate "timing" altogether? What's to time, if there's only one limb, or two, side-by-side upper limbs? Using the current geometry and designs of compound bows today, the top and bottom limbs/cams are supposedly designed to be working in synergy with each other, yet, in equal and opposite directions. Isn't the current goal to achieve identical timing/performance from each limb and cam at the moment of release? Wouldn't a bow using only one limb (or two side-by-side limbs) eliminate the timing grief? I'm the furthest thing there is from being a scientist/engineer, but I can see some potential for this design. What's your thoughts?
