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).

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. :)

The only thing I don't really get is the pink piece.
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.
Get it now? If not I will find a picture to post.
juneapaluna (author)  Oblivitus6 years ago
Yea I do but how is the second mag going to lock in place?
I just built this mod, it has a couple of fatal flaws. Don't build it.
Lol. I just wasted so much time too. XD.
juneapaluna (author)  Oblivitus6 years ago
I'm sorry to hear that, the plans looked good.
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.

ohh.
juneapaluna (author)  Oblivitus6 years ago
Ok, thank you.

DO YOU THINK YOU COULD TELL ME HOW IT SHOOTS I CANNOT WORK IT OUT
juneapaluna (author)  snarfit6 years ago
You pull back the piece called the firing rod in the back until the trigger goes up into place, next you pull the trigger kind of downwards until the ram releases and fires the rod.
