Re: More powerful (louder) "bird bombs"?

I have seen something on 37mm.com about a reloader losing a hand (or
at least part of a hand) after firing a homemade 37mm projectile. It
went off in the barrel!

Your recommendation of using a separate launcher for perfecting timing
issues is quite sound.

Thanks for the idea. I just kind of jumped into things without
thinking too much about the consequences. That usually gets me
"killed" in my paintball games. You may have just saved me the cost of
some damaged equipment or, worse yet, physical deformity or death.

How about materials for making that stationary launcher (mortar)?

I used PVC for potato guns back when I was a "kid" and, in retrospect,
that probably wasn't the safest situation either. It really doesn't
seem too safe to me with gunpowder.

How about plumbing pipe? Any other ideas?
