Step 1: Primary Barrel

Take a sheet of paper and fold it in half vertically (on the long side). Then roll this sheet in the opposite sense with a diameter about the size of your thumb. This will be the centerpiece of the SMG.

Step 2: Shaft

Take a sheet of paper and roll it into a long shaft to go through the barrel. The shaft will most likely be loose in the barrel. Repeat step 1 and stuff the barrel so the shaft spins freely but is not too loose.

Step 3: Pre-notches

Take lined paper and fold it horizontally three times. These strips will be folded five times (three of which will already be folded.) into small notches. The amount of notches formed will determine how many rubber bands the gun can hold. Make sure that you have twice as many notches as you want since they will be reinforced in groups of two. I used two sheets of paper for the gun I made.

Step 4: Notches

Heat up your hot glue and gun pair all of your notches in two. Glue each pair together by overlapping them.

Step 5: Finishing the Barrel

Take five of your notches and even space them evenly along one edge of the barrel. Divide the remaining notches into five equal groups. Glue the groups in line with the front notches on the opposite side. With enough space to place a string between them. Example can be seen in the pictures.

Step 6: Body

Take a sheet of paper and fold it vertically three times and then once in the opposite direction. Repeat this with four sheets of paper. Tape them in twos to give them support. Then make a hole (I used scissors) to slide the axle of the barrel. When making the hole, make it is close enough to the edge for the notches on the side of the barrel to be completely exposed (so that the rubber bands being shot don't get stuck in the frame of the body itself). Go ahead and hot glue a fairly long piece of string between two rows of notches.

Step 7: Rotary Handle

Repeat the steps to make a shaft. Then repeat the steps to make the barrel, only making it half the length (one more fold) and much smaller diameter so that the shaft is snug. Then make a hole directly underneath the hole for the barrel. Make sure there is plenty of room between the primary barrel and second barrel. The shaft for the rotary handle should be able to move freely.

Step 8: Bottom Support

At this point were almost done. However, it will probably be really wobbly. Take a sheet of paper and fold it vertically three times and fold up the two ends up about an inch. Then take two more sheets of paper and fold them vertically four times to form two tent-like shapes. Snip these two to fit between the support. Assemble the bottom support with hot glue and attach to the bottom. This will be the final length of the gun so glue the shaft of the primary/top barrel to the base and fold the ends of the secondary shaft forming a small handle on one side. Glue the secondary barrel to the bottom shaft as far in the back as possible.

Step 9: String Length

Wrap the string completely around the front of the back notches and around each ring of notches till the back. Then cut the string at the point where it can attach to the secondary barrel. Glue the string to the secondary barrel. Prep the gun for loading by winding the string unto the secondary barrel.

Step 10: Loading

All that's left is loading. Wrap the string in front of the notches, attaching a band every time you pass the notch. Once you've reached a full rotation, step the string down between the second ring of notches, attaching a band every time you pass the new notch. Repeat this process until you reach the back and have fully loaded.

Step 11: Firing

YOU'RE NOW READY!!! Simply rotate the bottom handle and the bands will start to launch from the gun.
