Picture of spring powered knex gun
Okey, this is a very simple gun, wich is made just for showing people how-to-use-a-spring-in-a-standard-block-trigger-gun.

shoots a fine 40 feet (with my spring)

If your just going to post something similar to stop posting this becuase its a block trigger, don't, i will come to you and haunt you (A).
This gun also can use some standard rubber bands, but i dont suggest it.


Step 1: Gather your parts!

get yourself:
1 spring, about 1 cm diameter and about 7 cm long.

1 rubber band, fo rthe auto cocking, as small as possible (even those tiny little half a centimetre ones will do!)

1 ball joint connector

2 blue rods
5 yellow rods
4 white rods
3 green/black rods
2 red/tan rods
2 grey/black rods

12 yellow connectors
4 white connectors
11 green connectors
2 red connectors
6 light gray connectors
24 dark gray connectors

you might want to add what kind of spring (extension or compression, extensions springs are kinda like a rubber-band and compression springs are the kind that you're using
altaria1993 (author)  firezone5 years ago
You can use both, if you use a compression spring you should just attach it on the other side of the ram and also attach it on the front somehow.
I know that I tend to be a smart alec at times but this isn't so much an Instructable as it is, a picture book. Being that I've seen many guns posted on this site over the years, your particular design caught my interest because it was intelligently crafted on a spring-based weaponry layout. This stood out quite well in comparison to the weak, noobish, and unreliable sea of useless rubber band driven hand guns. However this Instructable became a disappointment upon seeing that it had no instructions, thus reducing it to a mere suffix that is -able. While some are capable of creation from illustration, others, including myself, simply wait until this -able's author to bring enlightenment concerning the methods used to create such a weapon of ingenuity.
sweet name!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I got a spring gun that's as powerfulas the KK gun - making a magaazine for it. should i post it. P.S. If this goes 50ft. is about the same power.

it was a little to powerful but i once used an old broken airsoft guns spring (expect to used bracers/conforters on not just the fireing pin but where the pin hits the conectors.

You can get good springs at Lowes.
altaria1993 (author)  biggio8 years ago
sadly i have never saw one fo those on the netherlands
that stinks
altaria1993 (author)  biggio7 years ago
where would i find a spring big enough to fit around a knex rod??????
altaria1993 (author)  peanutbordeux8 years ago
get a (old) pen, get a strong boot (army boots :D) and stamp the pen, take the spring, pull it out in with, and voila, though you can also just by them ar a hardware store :)
you can easily find a spring in a Jumbo size Popup Push pop thats were i got mine, my gun shot about 50 ft. just smash the crap out of a [EMPTY!!] popup push pop thing and the spring is about 3 1/2 inches long or 10 cm for you metric peeps
altaria1993 (author)  lilpepsikraker7 years ago
i wouldn't know what the hell is a jumbo size popup push pop, though, if it works, i'm fine :P and about the metric stuff, dont start saying centimetres are for geeks... they are more accutare then "about one eight of an inch"...
i never said ANYthing about metric is for geeks!! please i just hate when people flame over silly things like this! :) Fire is bad.. whatever
reminds me of the gewher 42 in ww2
yeah a bit
yay coments!

i made something like this i used a bb gun spring and it was fairly powerful.
that spring looks like the one out of my brothers potato gun. too bad i smashed the whole thing with a sledge hammer. LOL
mrbox8 years ago
lol, i'm new to this but nice design i tried making it with a 5cm spring that fits perfectly around the knex piece. The gun launched a good 40 to 45 feet! Great Job, keep up the good work!
ive just built this and it really let me down, 3ft ..............................................................................................................
altaria1993 (author)  Flie-Ing GOOse8 years ago
then i suggest you get a stronger spring, mine went up to 40 ft and i used an old metal spring wich is a lot weaker then when i bought it ( 5 for €2,50) so you should really try and get a stronger spring, i designed it just so that it cna have a lot of tension to both the front and the back of the ram rod, so thets not the problem...
altaria1993 (author)  altaria19938 years ago
the € part should bve a Euro sign, and btw, 2,5 Euro is about 3 US dollars
altaria1993 (author) 8 years ago
have you guys also tried making it?
yea i did and it went a good 33ft.
