    Point me at the Right Design

    Post by Saxon Violence on Thu Aug 15, 2013 11:34 am

    Friends,

    I want to make a Small Relatively Light (To Carry) Crossbow.

    Crossbows aren't legal for Deer or Larger Game around here. It would be:

    A.} For Small Game;

    And;

    B.} Deer in some Hypothetical Emergency...

    {But I'm content with the Idea that Deer may be at its very upper limit...}

    I've never used a Crossbow. I was quite Content with a 45 Pound Longbow; and in Retrospect, I probably should have stuck to my Sweeter-Shooting 35 Pound Bow.

    Nonetheless, it would be nice to get Crossbow Performance comparable, to O say a 50 Pound Bow—if possible.

    And I'd like for my Crossbow to be easily to Assemble and Disassemble...

    And hopefully not too complex to build.

    Is there a Design like that?

    (I am willing to drop the Power Requirement Drastically. What Draw Weight would a Crossbow with a reasonable Draw length have to be equivalent in range and power to a 30; 40; or 50 Pound draw Bow...

    Real Bows !!!##$&*^^!!! Compound "Bows"}

    Drop the "Simplicity" next...

    Really do like "Light" and "Easily Disassembled".

    Thank You.

    Are you thinking medieval style or modern?

    Todd's question is the first real answer we need to really help you.

    For 50 lb longish bow equivalent you'll want a crossbow of 150-200 lb draw.

    For simplicity and ease of construction, Skane-type pinlock action is hard to beat.  You can combine ancient and modern by making the prod from something like fiberglass tension bar for chainlink fence, as I did here: 
    http://thearbalistguild.forumotion.com/t945-loose-laminate-pinlock-build?highlight=pinlock

    This has certainly proved effective against local-garbage-can raiding raccoons, and with good shot placement at my usual sub-50 yard desired deer range I would not hesitate to use this bow with the right broadhead bolt.

    A crossbow is generally 1/3 as efficient as a long bow.

    Meaning a 210# draw prod will be as efficient as a 70# longbow.

    For comparison I like to take draw weight multiplied by power stroke for a value. For example 50 pound longbow with 20" power stroke equals a value of 1000 which would be comparable to a 125 pound crossbow with a 8" power stroke.

    Nice Todd.  That yields an easy to understand comparison between bows of different types, like long- and cross-; and also a comparison within a type.  My 250 lb fiberglass tension bar prod with a 12" powerstroke versus, say, an Alchem 250 lb prod with an 6" stroke.

    Do you need to dissassemble it ?
    Fix prod to tiller with hinge so they can be folded parallel and fit nicely to quivier, fully assembled and ready.

    Been there . Done that.

    If you use one of the 120-150# fiberglass 'replacement prods' easily found on Ebay, you could use the commercial crossbow idea of a top slot with a screw and pressure pad from the front of the tiller for easy assembly/disassembly.  

    Use a piece of Big Box Store Oak 1x2 with wounded edges for a simple stick tiller, and a Pinlock action for simplicity.  Or glue up two pieces of 1/2" thick oak with a piece of 1/8" thin stock offset to make the bolt track, and still use a pinlock.
