Introduction: KNEX SHRAPNEL GRENADE/MINE/GUN

A simple design that fires blue ring pieces as a one shot gun,mine, and grenade.

And to all KNEX builders, it gets boring to see the same one shot gun made small over and over!
Please post only new guns with improvements or totally new designs!

Step 1: GATHERING THE MATERIALS

Get these pieces

Connectors
Green 14
Red 3
white 3
orange 2
light grey 6
grey 2
black nobs 4
sloted blue sphere 1

Rods
blue 10
green 19
white 4
yellow 2
red 1

Other
Any number of blue rings
Tape
String

Step 2: BUILDING THE BASE PARTS

Build the base as shown

Step 3: BUILDING THE TOP PARTS

Build the top of the grenade as shown.

Step 4: CONNECTING THE PARTS

Connect all the parts together as shown.

Step 5: ADDING THE FIRING MECHANISM

Add many small rubberbands onto the top and attach a red rod. Build the firing lock and slip it over the rubberbands. Remember 100 small rubberbands will last longer than one big one of equal strengh!

Step 6: LOADING AND FIRING

Use the locking pin and attach it onto the black nobs of the base and firing lock. Then fill up the red rod with blue rings.

Step 7: CHANGING MODES

For grenade mode tuck in the stand after loadting and throw.

For the mine mode use the stand and attach a trip wire to the locking pin. You may have to tape it down to anchor it.

For use as a one shot gun, use the stand as handle and push the pin.

check out the knex mp5 by ... manula or somthinglike that i forget. its very good and features a "real trigger" but the big red or yellow(not really that big tho) shoot better then the little green ones. the mag i for green tho. i have a mod that makes it AK except the best AK look doesnt shoot if you mod it off the mp5 but mostly just add the green connectors to the mag (you still get the same mag capaity cause the bullets dont load around bends) and make the barrel extension if you ever look at a pic of an AK it has a thik part where it leaves the stock then goes to a normal barrel sooo. but the gun is very good and it looks very good and it is sturdy and everything, except the upper/lower (it i that on a real gun idk what it is for knex) took some filing for me toget to fit. bit it is a very nice gun.

author
hobo lord made it! (author)hobo lord2007-02-20

try putting tape on the nobs and the pin so that it grips it more and does not slip off as easily

how is it triggered?

author
hobo lord made it! (author)hobo lord2007-02-12

When you put force on the trigger pin thing, it slips off and release the blue rings.

i built it and i admire the firing mechanism but i have only 1 elastic on and it just fires before i can even put the blue spacers on

author
hobo lord made it! (author)hobo lord2007-02-12

If you are having trouble you are probably not pushing it all the way into the holes, if you do, it will pop out and lock onto the ridges on the tips of the black nobs.
