That guy also made one that shoots pipe. Pretty cool idea to use hydro dynamics to your advantage and I respect the innovation.

That said, if I brought a huge, four band cannon to the lake I would get a few kill shots too

Me too in the early 80's;)..... tested a 1/4 scale one in the pool, my friend ( John Warren) thought I was nuts.
I'd be ranting on the phone about it and the speed of the tube and soon I would hear..."Don I gotta Go''.:crazy:

My first prototype model shot plastic straws completely through raw potatoes @ 3', power was rubber from euro race bike tubes.
I never killed a fish with it though.
He's got me beat on the I beam....never did that. I did do a 3'' 3/8 shaft in a 72'' inch barrel with 4 bands....very spooky to cock ...
Somewhere I have test target mylar from 20'' shots.
Cheers, Don

Haha nice a 2x4 with bands! That is a cool idea but i wonder on long shots if the flat sides of the shaft would cause it to drift off target.
