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  ! 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. |
