    I'm a 20 years old, male University student currently studying English Literature. I've been sailing for a long time, and I am very interested, but not very experienced, in outdoor activities.

     I've been interested in making myself a crossbow for a while now. After some online searching and several DIY videos I've found this forum. My goal is to make a strong, preferably long-range crossbow for practice and ultimately when I am assured that I can do it cleanly, hunting. To do that, of course, I need to learn how to.

     What I am stuck with right know is understanding what kind of prod I need to achive the things I want and I would very much appreciate if you could help me with that. If you think I should learn something else related to the subject before that, I am very open to any and all suggestions as I have no practical information about crossbow making and very few theoretical information about it. 

     Thank you for your time and knowledge.

    Three basic prod materials -- steel, wood/horn/sinew, composite/fiberglass

    *  Steel  - buy unless you're an experienced metalworker.   Getting delivery on a purchased steel prod 
         can unfortunately take 6 months to a year.
    *  Wood or wood/horn/sinew -  wood-only is not very powerful; wood composite takes a lot of 
        experience to build
    *  Composite/fiberglass -- wood-fiberglass composites are fairly easy to make (like a modern longbow or recurve, just shorter).  Solid (extruded) fiberglass is easy to buy and shape into a prod.  The crossbow in my avatar picture has a solid fiberglass prod of two layers, which draws over 250#, and cost a whopping $7 at a local fence supply store.   You can also use the extruded fiberglass "boat canvas support bars" in multiple layers to get differing draw weights.  Sail battens might also work to make a fiberglass prod.
          


    Draw weight -- a crossbow prod is, relatively speaking, about as powerful as a vertical bow of half the draw weight.  That is, a 100# draw crossbow prod is about the same as a 50# draw "longbow or recurve".  Prods of 120 to 250 pound draw weight are relatively easy to make/buy.  If I were you, I'd make a crossbow in the 200# to 250# draw weight -- not too heavy or too lightweight, good for target or hunting.

    Greetings! Adsz10
    Thank you very much for your answer. 

     I know a decent workshop nearby and I know a guy there who is fairly experienced so I was thinking about a steel prod. However I need specifications on length, width, thickness of the prod etc. I've done some measurements on a picture of a prod I've found online. (Pic relate)

     I came up with some numbers yet I would prefer your specs over my measurements.

    I'm not a steel prod kinda guy, so I don't have a dimensional formula for you;  hopefully someone will jump in with some specs.  Meanwhile, check out the Crossbow Building Wiki (link is on the right side of the main page) you may also find some useful info checking out some of the websites for suppliers found there.  TONS of info here, well worth spending time exploring.
