  • Limbs:
  • Shape and Cross-Section: Reflexed longbow limbs with a rectangular cross-section.
  • Materials:

    Two layers of Hard Rock maple are used to glue up the limb core. Veneers of Jatoba, a Brazilian Cherry wood, under clear glass, on both sides of the limb core, enhance the optical appearance of the limbs. Future wood is cut and ground for the limb wedges to create an optical transition to the riser. Reinforcing the limb tips with multi layered overlays from black and red micarta make the limbs suitable for today's high performance strings.

  • Width at Fade-out: 1-7/16 inches
  • Width below String Groove: 11/16 inches
  • Physical Weight: 17.5 oz (set of 64" limbs)
  • Finish: A satin two component epoxy finish protects the bow and enhances the natural beauty of the woods.

  • Take-Down-System:

    A black aluminium shoulder bushing centres the limb bolt and distributes the lock-down pressure over a larger surface area to prevent cracks in the glass. A steel pin in the riser and the protruding part of the limb bushing are used for positive limb alignment. A die-cut fibre type gasket between the limb and the riser should prevent squeaking noises when the limb is put to work.

  • Testing Parameters:

    A force-draw curve was obtained from the reviewed bow, using a digital force gauge with a resolution of 0.1 lbs. Measured bow weight was rounded to the next half pound.
    The different arrow speeds were achieved with the bow shot from a shooting machine with a mechanical release. The string was pulled to 28 inches A.T.A. (formerly A.M.O.) which is 26-1/4 inches from the string to the deepest point of the grip.
    The (3) arrows for the speed testing had a weight of 9 grains per pound of measured (not stated) draw weight. Speed measurements were taken 3 feet in front of the back of the bow with two chronographs set up in a tandem configuration. Each arrow was shot a minimum of 6 times and overall achieved speeds were rounded to the next whole digit.
    The bow was set up with my standard 16 strand Fast-Flight string, that features one metal crimp-on nocking point locator but no other attachments, like silencers, kisser button, etc.
    Note: Numerous tests over the years showed that arrow speeds achieved with my finger release, using a clicker, run 5 fps lower on average, than the arrow speeds with a mechanical release.
