Rubber Band Gun Schematic
These are the plans for a rubber band gun I am working on at the moment. It, and its packaging, is going to be my final for GD II, and I am getting quite excited about it. The bloodwood and curly red leaf maple are in the mail!
You should be able to figure out how it works from looking at the diagrams; the tension of the loaded rubber bands (up to 5) is key to its fuctionality. I am still debating whether or not it needs a spring to give the trigger some extra tension. I was originally hoping to lasercut the bloodwood middle parts, but at 3/8ths of an inch thick, our 30watt laser won’t be able to handle it. So, I am going to have to etch it and then cut it manually with a bandsaw. I am very fortunate to have cheap access to a laser for something as simple as marking cuts.

well, ah, nice looking plans they are but the trigger WILL need a spring. i also suggest that u test the parts before hand with scrap wood; there is a lot that can go wrong with these sorta mechanisms.
Hey John,
Thanks for the comment, however its been some time since this posting and the gun has since been completed. I made a number of mock ups out of plain old plywood to insure that the final production would go smoothly. I assure you, the finished gun does not need a spring on the trigger, but users have the option to run a rubber band from the bottom of the handle to the “hammer” to provide more resistance.
Thanks again!
what is the best material used to slow down the worn out..?
Very nice gun! I’ve been involved in a similar project, although more from a mechanical engineering perspective. I designed the mechanism out of aluminum and tool steel, and placed it in a hand carved maple stock. Take a look:

Thanks!
Jason: That’s a beautiful piece you’ve got there, certainly way more thought out than mine. Perhaps a collaboration is in order… looking to manufacture and sell your design? I can do some packaging for you!
Hey Andy, that’s a great idea. I totally love your package. We keep working on more and more advanced designs, eventually ending up with a clip-fed semi-automatic. When we get something really compelling, I’d like to have it manufactured and sell it. Thanks for the note!
hey can I have your gun?
