Juneapaluna's Knex Pistol




Introduction: Juneapaluna's Knex Pistol

This is the pistol that I use whenever im shooting knex guns. This gun was completely my own Idea and any look alikes are just simply coincidence. If any of you have good mods than post them and give me some credit within the instructable. If you do post a mod please let me know about it.

I hope you like my new pistol!

Step 1: The Handle

pic 1:make 2
pic 2: make 1
pic 3: put them all together with the piece in pic 2 in the middle. You can do so by putting in one white rod as shown in the picture.
pic 4: another view of the completed handle.

Step 2: The Trigger and Ram - Both Simple

Just make from the pictures. Very easy to do.

Step 3: Just Another Part


Step 4: Bottom of the Gun - the Barrel

If you have any questions just me, it might be a little confusing but I couldn't think of a better way to show it, please tell me if you do.

Step 5: Top of Gun

pic 1: make 2
pic 2&3: connect to barrel
pic 4: top view

Step 6: Connecting Everything

pic 1&2: connect "just another part" to the barrel and top part of gun.
pic 3&4: connect handle.
pic 5: put the trigger in, the trigger will not stay in place or connect to anything just set it in place as shown.

Step 7: Putting on Rubber Bands and Placing the Ram

pic 1: put rubber bands around the trigger pushing it up, you may need more rubberbands if you make your gun more powerful by adding rubber bands.
pic 2&3&4: set the ram in place as shown.
pic 5&6&7: add rubber bands around the ram onto the front of the gun as shown (make sure you put the rubberbands under the first three white pegs so your ram doesn't bend up).

Step 8: Loading

Update: Mag is fine with all the mods can double load but only 1 out of 15 shots about. pic 1: unhook the red connecter off the white connecter.
pic 2: swing the whole piece over.
pic 3: put five or six white rods in as shown.
pic 4:close the piece and make sure all rods are straight.

Step 9: Modifications

pic 1&2: add the piece to the front of the gun.
pic 3&4&5: add theese onto the part of the mag that moves and line them up with the piece made in pics 1&2 and you have a sight.
pic 6: make 2.
pic 7&8: place them here to reduce double loading.
pic 9: add a white rod right here to help the loading process.

    This is an OK gun for a second instructable but I've seen a k'nex gun very similar to it. 3.0 I think. :)

    Third should be much better if there is one, I have made better than this pistol with my own ideas but never decided to post.

    I have an idea shown in a picture I edited below. The green lines are elastics and the red ones are the elastics' pulling direction. This mechanism wil allow you to have two magazines ready at once. After you have emptied one magazine, you can pull it out and the other will snap into place. If you can make a similar design, it allow for double your current capacity.

    Wow that's a really cool idea, I will try that after I finish the sniper I'm building. If you do that as a mod then feal free to post it if you want.

    Okay, since your interested, heres are more advanced look at the system. The green line is a rod, the pink line is a piece that will slide forward on the rod when the magazine moves forward to be fired - this setup will keep the elastic band that pushes the mag down directly under the magazine as it moves forward. The yellow box is a couple of yellow connectors attached with a tiny green rod to push the ammo and magazine forward (otherwise only the magazine "pusher downer" would get moved). The black box is also shown in the first picture I showed you and it just something to attach an elastic band to. If you don't understand part of this just ask me about it. :)

    Edit 32.JPG

    Okay, the pink blob is a connector that the rear magazines elastic will be attached to and this connector will slide forward on the rod to maintain straightdownward pull on the magazine. It is a slide for the mag.

    Oh, I didn't mean literally lock into place, I meant it will move into the correct position and send ammo down to be fired. It shouldn't need to be locked into position, it will automatically deposit its ammo load.
