Introduction: Knex Rifle
this is the knex rifle I showed as a forum. it was mainly designed for looks and has OK range. its barrel is detachable and reduces range when attached.it has a carrying handle which is also detachable, and a bipod. it uses a basic hopper to load as I am not very good at designing new hoppers. feel free to alter or add to this design.
Step 1: Main Barrel
put together main barrel parts and combine.
(ignore extra parts in picures 4 and 5)
Step 2: Handle and Trigger
construct handle and trigger sections and add to main barrel
Step 3: Ram
making the ram
1, make these bits
2, close up.
3, make this
4-6, combine
7, add to main barrel
Step 4: Stock Part1
this is probably the longest and hardest step, so pay attention to the order of the pics and the orientation of the parts
1-4, make this part
5-7, make this part
8, make these
9, add them
10, combine
Step 5: Stock Part2
continue making the stock
1-2, combine.
3, make and add this
4, make this
5, add it
6, put on the orange connector
7, make and attach this
8 make and attach this
Step 6: Stock Part3
the final part
1, attach this
2, attach this
3, put these on
4-5, put through ram and onto barrel
6, attach black y connector
Step 7: Hopper
building the hopper.
1-3 make this
4 make this
5 combine and add to barrel
Step 8: Supports
construct the supports that go from the stosk to the main barrel
1 construct upper supports
2 construct lower supports
3 combine and add the grey connector
add to the stock (pic4) and the hopper (pic5)
Step 9: Carrying Handle
constructing the handle
1-3, construct the handle
4-7, attach onto hopper and supports
Step 10: Barrel
barrel
1-2, build this
3, build this too
4 build these
5-6 combine them
7-8 add these white connectors
9-10, make the front handle
11, attach
12-13, make these
14-15, add them
16, slide grey (or orange) rods up through the bipod
17, attach to the hopper and
18, add orange connectors.
you don't have to use the barrel, just don't attach it.
Step 11: Adding Bands
attach rubber bands to the ram and trigger as shown. the ruberbands are the same on both sides.
To fire, take off the hopper cover and load in up to 12 blue rods.
(11 for best performance) puul back the ram by pulling on the two yellow rods, and pull the trigger to fire.

Good gun, I've built it and made a few small changes to where the barrel joins the hopper, I will test it tommorow as its 4:21am :P

awesome, but I wouldn't advise staying up that late!

Strangly I wasn't tired when I got up 6 hours later. Sadly the performance of the gun isn't that great even with eight beefy elastic bands, maybe because it needs a shorter barrel.

yeah, the end of the barrel can be removed and it increases the range, but takes away from the overall look. and also, if you load one bullet at a time it should fire better, because of less friction.

The major drawback of this gun is that its effective with 12 bands as a gun that uses only 3. So somehow all of that power is being wasted.
Reply 13 years ago on Introduction
its because of the friction in a few key areas: barrel, hopper, stock and barrel extention.

Don't call it a rifle if the barrel isn't rifled.

Nice gun!!! I would make the gun if I had enough parts...I also just made my first gun and it doesn't shoot very far(6 feet). It is single shot and it uses a block trigger connected to a trigger at the handy part (sorry drawing a blank). If I add any more rubberbands the ram rod will break. Can anyone give me any advice? Oh and sorry for the long comment...

Put a Y clip ar a tan connector right before the end of the rod but before the connector on the end. This stops the end connector from slamming into something and breaking off. Like KNEX BUILDING IS FUN's idea, but using a knex piece instead of a band.

u can add ruberbands between the ram and rod to help keep them together it also acts a a crash pad fro the ram just rap the rubberband there

is it possible to build without the stock or bi-pod?
Reply 13 years ago on Introduction
or support?
