Penny Shooter

[Jared Haehnel]

I was wondering if an one had thought of making a rectangular barrel for a pneumatic that would shoot disks...pennies would be a cheap and easy ammo something like that.
And I would think they would be fairly accurate too.... just some food for thought...

The problem with a rectangular barrel is the low surface area available for the air to act on, as was discussed here.

However, there are other ways around the problem

....oops I missed that one in my search...thanks

It would be cheap for the first shots, but after a period of years wouldnt it end up being quite an expensive gun?

hmm.... why not go silver dollars for heavier projectiles? =p

didnt mythbusters do a nailgun to penny gun for the penny of of empire state bulding myth? Offcourse, they didn't use legos =p

didnt quite post like i wanted it to.. but anyways.. i mean go from the size of a penny to a big bore size to have a nice big ass explosion in the chamber.. but ahve the been seal it off.. to make it fly with the entire force of the cmaber

cool paying from 100m distance
but how to get a barrel that fits them exactly ?
and yes it would be expansive
and if you throw a piece of carton (try) then it doesn't fly in one line so wouldn't this happen to the penny ?
but just try to make a proto type so you can see what will happen
and you can still make lead slugs to have cheap ammo
