well if they aint sub chamered I would prefer to say that they are more like a one end open pipe bombs in my eyes
read the building instructions in the stickies here at the top first and think it over a few times before you build any more cannons
hard words ?? no not at all , just a friendly advice
are the breach plugs shrink fit or only welded ??
how long is the breach plug ??
You probably not got any problems yet with this construction , but you most likely will have in the future
remember that this is actually a pipe bomb when you lit the fuse in the future
do you want to harm or kill yourself ?? if so there are easier ways to do it
THERE IS ONE RULE OF THUMB YOU ALWAYS SHOULD FOLLOW WHEN BUILDING A CANNON
THE SAME WALL THICKNESS AS THE BORE SURROUNDING THE POWDER CHAMBER AREA
I must say that Im happy that you found this board now and not after there had been any accident
maybe they will hold together for a lot of shooting before they explode, but you will never know when that will happened , the barrel doesnt give you any warning before they burst .
if you have sold or given any cannons away with this construction I would track them and get them back asap
if something happened with one of those barrels you would likely be sued for all you got and probably much more for liability reasons .
even if its your best friend , when your cannon have killed his son I can tell you that he is not your friend any more .
think this over very very carefully and ACT asap
please dont even try to convince us that your barrels is safe , we have read more then enough news reports and even police investigation reports about such one end open pipe bombs to be convinced that they are safe to use . most of them had been used for years and some for decades before they burst , so think this over very very carefully .
you seem to be an very active producer of this pipe bombs , the more you make of them the sooner one of them will burst and kill someone
the welding of the trunnions didnt look so good , so if the breach plug is only welded by the same "skilled" welder its an dissaster
the breach plug got approximately the same weight as the ball I would guess if you are using steel balls .
so if the weld cracks it will leave the breach with the same speed and weight as the cannon ball , do you want to stand behind the breach when that happened ??
this is critisism ok , but its positive critisism .
none of us here at the board want to read about you or some in your family as a number in the statistics
PLEASE TAKE THIS WORDS VERY VERY SERIOUSLY
