This is the ammunition - large rubber bands. I don't know how many it can hold I've put 6 thick ones on. I only have 2 thin ones but it could probably hold 7-8. It is extremely powerful and because of this extremely accurate. It is powerful because the gun is life-size and the rubber bands are attached to the front and back, it stretches them a good 29 inches (the gun is 32" long - like the real one!)
These are pictures of the magazine. The magazine has a spring in it and can hold about 20-30 (not sure) of 'Thomas Coopers' bullets. It was intended to fire lego bullets, and I didn't change the magazine. On the last photo you can see the magazine release, when you push the button on the side (which is spring loaded to be pushed back out) it allows you to pull the magazine out. If you do not press this button the magazine won't drop. the rubber band to pull the trigger back is also attached to the magazine release so it doubles up to two mechanisms. The firing ones the same, it is also part of the cocking arm.
The Whole Gun | The Lego Gun:
This is the whole gun,you can here see the stock aswell. At the back you can the iron sights that are unique to the Thompson.
Here is the main body of the gun. You can see the gun cocked, and how I've changed the side - by giving it a bevel. One picture shows the gun open, how you load it. You can see the magazine release button on the side.
This is the gun field striped, I made my Thompson's stock come off, the magazine detach and the grip and barrel come off. The real ones body splits too. Whilst taking the pictures of the mechanism, i 'accidentally' pulled the top bit off, the 'L' shape in Bohdan's mechanism and trigger are in the bottom half the rest in the top! They're not attached! so I accidentally made the gun better and more like the real one!
Here are 2 pictures of looking down the iron sights and one of the front sight - you can see other pictures of the sights on the main gun. The sights at the front and rear line up and are accurate. where the sights are is where the elastic band will go (You can see in the videos I hit the target every time).
Here is the mechanism - its so small and compact it fits into 2 (or 4 counting the walls) there is no sign of the mechanism on the outside apart from the odd pin. The cocking arm is resting on the mechanism - as shown in the pictures, so everything is hidden by it and one wall. Its a modified version of a mechanism by Bohdan Tkachenko click here to see his version. With mine the cogs are all on the inside, it took ages and is quite complicated.
Here is a video showing me shooting the gun at 3 minifigures (the minifigs are my WWII ones - without helmets)
Notice: No minifigures were harmed during the making of this film
With regards to instructions, I won't be making them at the moment. I may make some for the mechanisms (firing & magazine release) later this year but it is unlikely that instructions for the whole gun will be made... sorry.
