    Renaissance Sporting crossbow

    Post by tony a on Wed Jun 14, 2017 12:44 am




    This is my rendition of a renaissance crossbow. See photos and how the parts were made and material used.

    A. American black walnut, used one of my rifle stock blanks.
    B. 3/16'' micarta for the top surface, butt end, and trigger plate.
    C. 1/2'' rosewood for bow retainer and rear butt end.
    D. 3/16''1018 steel for the bow irons.
    E. 3/4'' rd. bar 1018 steel for the three nuts.
    F. 3/8'' sq.bar, 3/4'' rd.bar 1018 steel and a lamp part for the trigger unit.
    G. 70 lb. alum bow from New World Arbalest, used alum black to color the bow.
    H. Delrin for the nut.
    I. Ebony for the nut cradle. Note made two cradles one from Chakte Viga hardness 2750, and Ebony hardness 3220.
    J. Brass applique rosette and leaf for decorations.
    K. 1/8''x 1/2'' and 1/4'' sq. 1018 steel for the trigger safety.
    L. 5/16'' set screw and nut retainer pressed into the rosewood to apply pressure to the bow.

    The prod is 70 lbs. made from alum, I also have the doubled ends heavy bow string made by Dave Watson. I will not be using the crossbow it will be hanging in my office, as I have admired the design of the crossbow. and always wanted to make one.

    This is a beautiful piece! I haven't been on this forum for a while, it's great to catch up on some great builds. I'm intrigued by the bow irons. It looks like they're just installed with that bolt, with no tension to tighten the prod into the mortice to make it secure through the repeated shock of firing, like you would get with wedges or screws to tighten the irons down. Is your fit just that precise, or am I missing something? Again, just beautiful, love the peep-sight, too.

    Good show Gnome, I was curious if anyone was to ask this question. The bow iron stock hole is positioned so as to have tension during assembly with the irons, by bending the bow to line up the iron holes and installing the 5/16" bolt is now under tension. Note the stock hole is lined with a steel tube  bonded in the stock for additional durability. For additional tension a 5/16" set screw in a retainer nut pressed into a rosewood block is then tightened against the bow. See the photos they show all these details.

    Interesting. I had to give that some thought to make sure I understood what you meant. How far do you bend the bow when mounting the prod? Just enough to provide tension when the bow is unstrung, or far enough that the irons are still under tension when it is strung? Sounds like a pretty elegant solution and I am compelled to experiment with it. Is there a historical precedent?

    No more then 1/2" to bend the bow to align the holes and install the bolt. No historical precedent that I know of just a simple engineering application.
