**5" at the least

    Great instructable,I used a 18 inch lenght of Perspex instead of saw blades which made it ridiculously powerful and modified the trigger a bit but thanks for the idea

    not really its just a hacksaw blade and hacksaws arent sharp....


    Reply 8 years ago on Introduction

    Actually, hacksaws ARE sharp. Have you ever been cut by one? It hurts like #311.
    Hacksaw blades may have small teeth, but those teeth pack a pretty nasty punch.

    maybe use a thin, bendy piece of wood thats somewhat strong (i suggest those free paint sicks from home depot cuz they are bendy and strong and free. maybe also invent a better trigger system(like a real crossbow) just to make it more awesome :) i like it.

    thx dude;D
    i prefer the later 14th century crossbows(steel) than the earlier versions of crossbows which were often a stick attached to a bow of wood or a bow of wood,sinew,and animal tendons.all in all, steel limbs are more efficient when making a crossbow because it wont snapXD


    Reply 9 years ago on Introduction

    snapping can ruin a bunch of hard work so good thinking

    lol, this is better than my other crossbows which aren't really crossbows, but are more like crossbow-like paper crossbows. Thy shall subscribe!

    Torsion is twisting, I think this is tension-pulling force.
