Re: New quest - RBG's for fencing melees
- Thanks for your ideas. I'm working on plans now, and if they work, I'll try to post them for use by others.

If you could check out the yahoo group http://groups.yahoo.com/group/SCA-Gunnes
There, in the files section are several articles about band-gun construction.
Thanks for you help with my last request - on to the next one. I've been asked to make a number of rubber band guns for fencing melees. I can handle the wood and the metal barrel, but I need help figuring out how the trigger/release mechanism functions. Has anyone seen plans?
Thanks in advance.
