Well thanks. I put a lot of time and thought into making it look more like a gun and less like pvc, and I appreciate everybody's comments.

Yep. Totally PVC (well except for the trigger of course).

if i remember correctly, its a 1.5:1 ratio.

all in all, it probably cost around $60. Not bad...although now it just sits.

No, there's a chamber under the barrel. It's an over/under design.

i've already sent pimpmann my info in the right format, but i dont think he's put it up yet...

well, unfortunately it was designed as i built it. All I can tell you is what's in the description. 53" tall, chamber and barrel volumes, 1" sprinkler valve....thats just about it. everything else was designed as i went along.

Yeah, I want to enter it, but not sure how exactly. I've read the contest info. Any help??? Oh, and the next will probably be a tennis ball, golf ball, or bouncy ball launcher. Might even make my own piston valve instead of a sprinkler valve.

I'll also mention that all the pvc logos/writing was sanded down so the whole gun is smooth. Plus, before it was painted, there were no cement stains!!!

wow...thanks for all the comments. The handle is from an old Spyder One pb gun I had from years ago. The "stick" on top is the breech loader. Think I'm gonna shorten it a little though...make it less obtrusive. The trigger actually pushes open the blow gun that actuates the sprinkler valve. The blow ...
