Well, this gun has failed again. This time, a large chunk of the chamber blew off. NEVER use ABS for combustion guns!

Actually, I am just kidding. The safety aspects I took into consideration when building this launcher seem to be working, as it has seen over 100 shots without issue.

People should not be afraid of their governments. Governments should be afraid of their people.

Can you post a picture of the failure?

It is possible that the first failure weakened the chamber in some way that wasn't visually apparent. You did cut off the broken part from last time, right?


HA! I figured out why it failed! ;

I would have thought that after an abs one blew up you would start using pvc, maybe now you will.

Who cares about whited text. To be honest with you, I've been waiting a long long time for the chance to quote you renouncing ABS.

It looks like he used a threaded male pipe adapter, not endplug. Seems like a pretty obvious solution to me...
