For my first instructable I decided to make a mini knex bow. This bow does not require a lot of pieces and is way more powerfull than I expected

good job. i like the look of the whole thing. generly bows are more powerful because of the shorter berral and no need for a ram.

who thinks i should post my full size bow?
Sgt.Waffles says: Mar 16, 2008. 7:22 PM
Do it.
Ltcheesecracker says: Mar 19, 2008. 7:55 AM
done.

Because... Direct transfer from rubber band to projectile instead of rubberband to a ram then to the projectile.

Actually, when a large object hits a small object, the small object will travel faster than the large object was initially moving. So using a firing pin will shoot harder with a well-made gun (unless the bullets are bigger than the firing pin).
geodez says: Apr 10, 2009. 5:04 PM
actually the ram makes it go shorter i have theoretical and practical proof because energy is lost in the transfer from the ram to the bullet in the form of sound and heat which is also lost from the ram traveling down the barrel. this is the practical proof, think of any slingshot mech gun such as the sr-v1+v2 the sipriani rifle they have good range but a gun with a barrel and ram of the same size will go shorter. but i do admire your reasoning oodalumps.
oodalumps says: Apr 10, 2009. 8:22 PM
An intelligent response from an Instructables Knexer? I thought it was impossible. You are right that firing pin guns are inefficient. So I guess one could argue for both sides. It depends on the gun. But generally a slingshot will shoot large ammo better, and a firing pin will shoot small ammo better.
geodez says: Apr 11, 2009. 12:48 PM
agreed

mrbox says: Jan 11, 2008. 5:48 PM
WHY does it look sort of like mine...? I dont have an instructable but seriously that looks similar to mine only mines more of a ... structural - ish (more supports to hold more bands) type of bow..
juneapaluna (author) says: Jan 12, 2008. 7:02 AM
idk.
GorillazMiko says: Jan 10, 2008. 4:23 PM
This is really cool and easy for a first Instructable. The pictures are okay, but I can easily see them, and everything else looks good, nice job.
juneapaluna (author) says: Jan 10, 2008. 5:13 PM
Thank you.
Whaleman says: Jan 9, 2008. 7:47 PM
It bears a striking resemblance to a "Compound Bow" posted yesterday....
cowscankill says: Jan 10, 2008. 2:08 PM
it looks a little improved though...
Loosewire; SOE Operative says: Jan 10, 2008. 1:22 PM
A happy coincidence? :P
Whaleman says: Jan 10, 2008. 8:06 PM
Oui!
juneapaluna (author) says: Jan 10, 2008. 3:37 PM
Yea, I didn't try to make it look like his.
Whaleman says: Jan 10, 2008. 8:05 PM
