I'm not sure where else to put this but, I have been trying to experiment for a little while with PVC pipe to launch golf balls or tennis balls or something. I figure most people can't throw it far enough to actually get a decent challenge out of it, so why not build a pvc pipe launcher. I think it would be cool to make a little project discussion to see if anyone else has tried to make some form of a target launcher. Otherwise it would be cool to have people drop in ideas for launchable targets or target launchers, and like I said, get a little discussion together. Any thoughts or ideas?
Personally, I was looking through my hardware store for a reasonable spring, with a pvc pipe. I could have a system like a cross bow to either pull the cocking lever back or, to push it down towards the ground to cock. Then have some sort of pin or trigger mechanism to launch it. Well thats at least what I have been playing with.
