Rubber Band Gun

I just wanted to share my build of a rubber band gun build that I have been working on over the past month. I am still making revisions to the gun to help with assembly and the functionality. Some of the issues I am running into are the spinning of the barrel tends to jam once it gets going and over spins. Take a look and let me know if you have any ideas on improvements that might help with the string over spinning.



Interesting model.

Terrific design and the picture of your table full of parts is kind of funny. I a little bit am picturing Tuco in the gun shop from the Good the Bad and the Ugly.

Is it spinning too freely. Need more friction?

It is definately an issue of spinning to freely. I just need to come up with a better way to add friction to the barrel the current meathod does work but looks a bit odd and I am really tring to get a good look as much as functionality.


Baltic Birch plywood will be stronger and likely more layers.
Keep us posted on your development.


Just wanted to post an update have another video out there on this build. I am going to add one or two more focusing on the electronics and the mechanical functioning of the rubber band gun as I move into those parts.

This is a bit shorter then the other build video still around 30min though. I tend to get side tracked when creating videos!
