 | | 28 Jan 2009 01:50 AM | | I've received approval for my burst disc cannon design, after rigorous testing, and I'm pretty stoked. It's a single-shot, single or multi-barrel, cheap, lightweight, cannon meant for torps. | | | Still a proud member of the AUSBG! | |

| | 03 Dec 2011 05:58 PM | | Ok, here it is, in all it's simplicity. 
Barrel, retainer, body. 
Retainer fitted to body, no burst disc fitted. 
Assembled cannon. | | | Still a proud member of the AUSBG! | |

| | 04 Dec 2011 03:41 AM | | Wow, that really is simple, what did you use for the parts?
Looks like it would be good for sub torp tubes. | | | |

| | 04 Dec 2011 04:14 AM | | This cannon is for HMS Rodneys submeregd torps. Haven't used it in combat yet, I keep forgetting it's there.
One day a merchant will hug my bow, and pay the price.
The body is made from a 1-3/4" to 1" PVC reducer and a 1-3/4" end cap.
Internal volume is about 65cc.
The threaded section, retainer and cap were recovered from a hair dye bottle. (no, I don't dye my hair, my wife dyes hers).
The brass parts were turned on my lathe from stock with the barrel flared and slid in from the back, and epoxied in place.
The size of the hole in the brass part determines the burst pressure, and you'll need to use a bit of trial and error to get that right.
I use a section of disposable latex glove for the diaphragm.
There's a small magnet embedded in a lump of metal putty at the base of the barrel, to hold the 1/4" bb in position. | | | Still a proud member of the AUSBG! | |
