Rubber Band Gun Plans Pdf
These look great! Excellent work. I have a couple of these plans, and I intended to download the others, however it looks like the rbguns site is no longer working. I would love to build these for my son this Christmas, curious if you have some of the pdf to share? Thanks for posting your work for us to see.
Rubber Band Gun Plans Pdf
They have detailed PDF plans for free download for making a variety of different guns. Videos showing them in operation too. I particularly like the lever action rifle, and the lever action works too!
This super fun rubber band gatling gun project can be completed in a weekend with inexpensive material and basic tools that most people already have. There are easier ways to make some of these parts using expensive specialized tools, but we tried to make the entire guide more accessible by using basic available tools that anyone can use.
The plans and templates are available for FREE to download on this site, and the method shown in the videos and described in this instructable will make it easy (even for a novice wood worker) to complete this project and start slinging rubber in no time!
The gun can shoot LOTs of rubber bands, the only limiting factor to the number of rubber bands it can hold is how many rubber bands can physically fit on each barrel without slipping off. The limit is very high though, and should be ample ammo to dominate any rubber band gun fight!
There is a process to loading the rubber bands, and it's a little tricky at first, but by watching the video on how to load the rubber band gun, and practicing, you should be able to master the process in no time!
Each barrel will have a curved edge and a flat edge. The curved edge will point forward on the gun, and the notch is to hold the rubber bands in place. The flat edge will sit in the rear of the gun, and needs to be flat to allow the rubber bands to be pulled up and over the back of the barrel to launch off when spinning the hand crank. The 1/4" dowel pieces will rest against the rear flat barrels to make sure the rubber bands don't slip under the rear of the barrel (which again would restrict the rubber band from launching off of the barrel when the hand crank is spun).
We chose 12" is our barrel length. We felt this was a good length with many rubber bands available in that size range. If you want a longer or shorter barrel, now is the time to decide. We measured from the half circle end and marked 12" on each dowel. We then used the Jig saw to cut them to length. We repeated these steps until we had 10 separate barrels.
While we were cutting the barrels, we also cut out the 1/4" dowels that will work as the stopper for the rear barrel rubber bands. The length of these can depend on how you assemble your gun, but we chose 1.5". Make sure and cut out 10 of them (one for each barrel).
NOTE: This is also where you can make this either a right hand or left hand rubber band gun. But choosing which side the horizontal string guide will feed the string to, will determine if you wind the crank with your right or left hand. I am right handed so I placed the horizontal string guide hole on the right side of the gun stock.
Barrel Rotor Assembly - I used rubber bands to hold this together, then I put glue into the front end and let it dry. It is easier to see in the video how to do this, it's much more difficult to explain. Don't glue the rear rotor (the one with the 1/4" holes in it) as you will need to space this once more of the gun is assembled and then glue it. Again, this is shown in the video more clearly.
Rear Barrel Rotor - Now that I had the spacing figured out for the barrel rotor and spacers, I was able to glue the rear rotor in place. Just like the front rotor, I leave the rubber bands on and just separate the barrels from the rotor enough to slip a little glue in between them.
1/4" Dowels - I just rolled the ends of the 1/4" dowels in glue, and stuck them in each hole. These need to lay flat against the barrel (any space between these will allow the rubber band to slide under and behind the barrel and will cause mis fires). If the dowels were fitting right up against the barrel, I just used a rubber band around the 1/4" dowel and the barrel to make sure it dried making contact.
The basic idea is that you place the string over the barrel first, then stretch a rubber band over top of the string. Rotate the barrel one over, and repeat the whole process. You keep going round and round the barrel until there is no room left on the barrel for any more rubber bands. As long as you place only one rubber band over each layer of string, you can keep going around the barrels and load multiple rubber bands per barrel. They will shoot off of the barrel one at a time as you wind the string back up.
Here are some pictures of the finished Gatling rubber band gun. If there are any parts you want better pictures of, let me know and I'll update this section with more detailed pictures of the final gun.
You should be able to freely download the plans, you don't even need an instructable account to do it. On step three, there are links to the PDF plans, you can either click them and open them up on your computer and then save them, or right click them and save the target as. That is the best way to get the plans. I just tested it in a different browser (that doesn't have them in my cache) and without logging in, and it worked fine, give that a try and I hope the project goes well!-Mark
