Introduction: Home Made Tension Crossbow(no Rubber Bands!:D)

About: i <3 smoke

in this instructable i will show you how to make a simple crossbow that uses hacksaw blades to create tension on the string instead of using rubber bands. i dont know i was just sick and tired of people making crossbows with rubber bands...so i invented the only crossbow on instructables.com that uses tension to shoot!!!!!!!!!!!!!!!!!!!!

Step 1: Tools/materials

tools:
scissors
a standard use saw
a work bench
1 clamp

materials:
a clothes pin (the one with a spring)
some duct tape
a long* piece of string}*
a piece of wood (1" x 1" x 5"**)
and last but NOT least:a **couple** of hacksaw blades

*depends on how far you prefer the "crossbow limbs" to go back
**5" at the least
****use more than 1 to get maximum torsion from crossbow!!!!!!!!!!!!!!
}*dont use yarn type string(soft and springy) try using twine or string bought at a hardware store

Step 2: Step 1

first you need to make the stalk of the crossbow.the pics will lead the way...

Step 3: Cut the Tape

like so...
then attach the duct tape to the clothes pin like so...

Step 4: Attach to Stalk

title is pretty explanitory...

Step 5: Make the "limbs"

just take a bunch of hacksaw blades,bend them to desired shape,and tie a couple of half hitches at the ends.(note that i only had one hacksaw blade at the time...)pics will show you how to tie the right knot.do this once then twice to be on the safe side.

Step 6: You're Finished!

now that you've made a crossbow,wouldn't you like to know how to use it?of course you do!
1)put c/bow in dominant hand
2)push down the clothes pin
3)pull back the drawstring to the clothes pin
4)let go of clothes pin
5)add ammo to front of clothes pin (ex.:pen,straight stick...)
6)aim
7)push clothes pin and tada!!!!congragulations! you have officialy killed something illeagaly!!!!!!!!!!!!!
;p

    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....

    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.

    theyre not sharp if u dont use em like a saw lol >.>

    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

    snapping can ruin a bunch of hard work so good thinking

    why not carbon fiber?

    i dont gotz any:( (im not very resourcefull)

    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.

    o lol i knew it was 1 of those two forces...
