Double Barrel Rubber Band Gun
Are you ready to blast away any target with loads of rubber bands? Then this project is for you. And the best part is this is a simple upgrade from my original design. If you have not seen the original Rubber Band Machine Gun, follow this link:
Go watch that video and then come back to this one for the upgrades.
Here are the additional parts you will need for this project:
2 – T-connectors
2 – Elbows
4 – 3-inch pipes
6 – 11-inch pipes
1 – 12-inch pipe
11 feet of 550 Paracord
First you will need to make another set of barrels just like the first video. This does take some time, but be patient and make them correctly. (OOPS) If by chance you build the barrels and have all of the grooves facing the wrong direction, just like I did on the second set, here is an easy way to fix that problem.
Take an additional piece of 1/2 inch CPVC and wedge it into each barrel. Then cut 6 more pieces of 2 and a half inch long pieces of PVC and slide them over the CPVC. Add some hot glue to hold them in place and cut off the other end of the barrels. And use a file to smooth both ends.
With the barrels done, lets work at the frame. In place of the corner connectors on the right side, we want to add T-connectors. I then connected the 12-inch pipe to both of the corner connectors and placed the remaining 3-inch pipes into the corners. The new section now slides into the T-connectors on the original project. Now using the elbows, add the new barrels to the frame.
When adding the paracord, make sure you have both spinning in the same direction or the cords may become tangled. I taped one to the top and one to the bottom of the 2-inch pipe so that they would start firing at the same time.
You are now ready to load those rubber bands and blast away the competition.
And there you have it, a DOUBLE Barrel Rubber Band Machine Gun.
