    Glad to be here. - Working toward building a completely unreasonable machine

    Post by JimKS on Sat Jun 28, 2014 10:13 am

    Hello. My name's Jim. 

    A week ago I found my seven year-old grandson using a makeshift slingshot to evict the pest metropolis colony outside the cottage. I joined him for a little while. He remarked that if we took our job seriously, we'd be using a crossbow. My inner seven-year old agreed. Although my inner law-abiding citizen wonder whether harassing canada geese with a stick slingshot legally differed from neutralizing canada geese with a medieval weapon. Ultimately, we decided it'd be fun to build one but we'd have to find another way to evict the geese. He and my inner seven-year old also decided that the crossbow needs to be at least as powerful as physics and our abilities allow us to make it. 

    Later, my son/his dad volunteered to help.  My son and I only ever repaired things together, we never worked on anything together just for the sake of doing it, so this project will be something special for the three of us. 

    I was a carpenter but have experience in fabricating and metal work. My son's a mechanical engineer. So we've got a useful set of skills for this. But neither of us have built anything like this before, and we questioned the viability of our designs. I'm glad I found this site.

    Welcome Jim;  The answers to most of your questions can be reasonably easily found here or in the Crossbow Building Wiki (see link at the right of the page).

    The biggest starting question is "What kind of action (also called "lock" or "trigger") do you want?"  The Skane style pin lock is pretty darn simple.  The classic roller nut-and-tickler action isn't "rocket surgery' either.  More complicated "multi-axle" actions step the complexity figure up as much or little as you're willing to go.  

    Prods don't have to be metal -- they can be PVC pipe, fiberglass bars, wood, wood-glass composites and other exotic materials.  Look at the prod in my Avatar picture, which draws well over 200# and was made from two pieces of fiberglass chainlink fence tension bar, and cost $7.

    Tiller designs range from nearly straight sticks to futuristic fantasies.

    Physics and abilities should easily allow you to build a 250-350 pound draw weight bow.

    When you've don't some homework reading here in the Crossbow Building Resouces & FAQ, and you've got questions, just ask.  The only dumb questions are the ones you don't get answered.
