Hi all
The name is simple... it shoots spuds froma 1.5" barrel (I can think of anything better)
This is my first cannon.
It's a basic cannon with a wooden handle.
From what I could see in my dusk test it shot across the yard (aprox 200')

NOTE: the pics are sooo out of order... I can't get them fixed.

Very nice, it looks pretty clean. I like the wooden handle. Might I suggest propane metering next?

nice handle, it could use some paint, and id recomend a neater tape job, or plumbers tape(metal straping that tightens with a screw assembly). oh, and please take 30 seconds to remove the white price stickers from your assembly pieces, i really like the look of the gun, but the stickers just make the appeal dive. otherwise great job

You did a good job on the trigger handle...the cannon as whole however is rather sloppy....probably one reason it stopped working for you.

It's a reasonable effort for your first try. However, don't waste time repairing it, just start over with your next improved model.

For you new cannon take the trigger and handle off your first one and use it on your second one.
