Since I really don't have any good tools for my lathe yet (i.e. o-ring cutters aka parting tool or a boring bit) I decided to use it to drill some nice centered holes.

The chamber, seen below, is a 2 by 8in pipe nipple, reduced down to 1/2 inch for the barrel.



The ignition source is a bolt, drilled through, with a wire superglued into place, somewhat like a sparkplug.

I've had this gun for about a month now, I was just a tiny bit afraid to post it, seeing how huge the Orange Bomber was. Makes this gun look a weeee bit pathetic.

Looks nice 8) ! What propellant do you use? What is your longest shot? I wish I could make one like that but A) I cant afford a lathe C) Im only 14 and my mum probrably would not let me get one and C) I cant find any places that sell metal tubing that big! Nice gun though !

I use regular Right Guard Deodarant, but I recently installed a propane injection system, which I have yet to get pictures of. My farthest shot was about 150 feet with a AA battery.

Being my first metal gun, this one turned out pretty ell, but there are some things that I am not please with. It's hard to get a good fuel mix in the chamber, which most of the time gives less than mediocre performance. I think the next metal combustion I make is going to be a bit smaller.

I would like to see a cannon like you have built out of metal in a 4" or bigger chamber ,with a 1.5 o r 2" barrel ,say 4 to 5' in lenght.has anyone ever done that? you could outfit it with a shrader valve and pump in a little air to beef up the power a little,not too much though or you would be better off having a remote ignition device like I have on one of my cannons, so I can be 15' away when it fires.

wow thats cool.what do you use as ammo.

AA batteries are my ammo of choice.

He said AA batteries. Please read before you post.
