    Looks great so far, is the prod all wood no glass?

    Curious to see how the trigger works.

    No, it has a layer of clear glass on the back. It goes: belly, ipe in two layers, hickory, purpleheart, glass.

    Looks sharp, can you explain the slide action part? Hope your riser is strong enough. Here is a picture of a proline crossbow. It is the only crossbow that I know of that uses a wood riser with 2 separate limbs. It looks quite a bit beefier than yours but don't know if that would work with your design.

    Still I hope yours works out.

    I wondered about that myself. It is reinforced with fiberglass on the bocote faceplate and backed with two bocote teardrop wedges but you may be right. I am considering a front stainless bridge to tie the two sides both layers together and prevent separation of the faceplate. I wanted to avoid it but it worked well on my cocobolo elephant bow. It's just heavy and slows arrow loading.

    Here are two other wood, split limb risers I have made, both very successful but they are tied at the top by steel. First bow is only about 90# but this one is about 200#.

    This current bow started as a single limb bow but I couldn't stand the loss of performance I knew I would have with pressure on the barrel not to mention shorter string life, the pulling upward on limb tips etc.

    Cool stuff they look awesome!
    The wooden prod mountings are great...
    Are the prods symetric and centercut and what does "slide action" mean?

    Look at page one wil. There are a couple pics.
    The prod is pressed and cut in half. Slide action refers to the gastraphetes style cocking mechanism.

    I am currently working on the 4th generation prod design for this bow. I am trying to get the most recurve I can practically engineer into the prod. One broke after 100 or so shots, one began to delaminate due to too thick of a hickory core and the last one was too heavy and began to split at the limb tips after 60 or so shots. The next one will have a bamboo core, osage and glass belly and hopefully be perfect. My goal is to push the limits of arrow speed without going to a compound design. I could have easily just made a reasonable, safe prod but where's the fun in that?
