Beautiful Piece!! Aren't dads great sometimes... 8)

This reminds me of something that would have come out of tv show and even the Will Smith movie "The Wild Wild West". Based in the late 1800s, they were coming up with all kinds of cool mechanical contraptions to save the day.

If you have the inclination, I would love to see this thing in operation on video.

The chamber is made from a Naval shell casing, WW1, along with most of the other brass work, all picked up off car boot sales for not very much money at all.

The only major parts bought new were the barrels, 28mm copper as brass would have been ridiculously expensive. Some other small bits, like gas fittings were also bought but the majority was custom machined from
stock. In total about £70 spent, but a lot of the material came from 'stock' so hard to tell what it would cost to make if you bought everything.

I've been modifying the ignition recently as there was some scorching on the wiring inside the chamber, but a couple of weeks ago when we last fired it we could get about 7 seconds repeat time, for as long as you want to keep going. I expect with a bit more fiddling and a well drilled team for reloading that will come down to about 5 secs or less. Not exactly gatling speed, but that was never really the point of this project.

As soon as I get it re-assembled (when work stops getting in the way of my free time) I'll have a go at some video clips, might be a week or so though as work taking most of my attention at the moment

If you want to embark on such an ambitious project and need diagrams, three months is probably a bit unrealstic - it's more likely to be your puberty project ;)

My apologies, I took the complete lack of punctuation and tone of your post to be an indication that you were a lot younger, ah well.

I do not feel worthy letting my eyes bask in the glorious amalgamation of brass, wood and copper you have here to create a cannon. (haha nice clip iknowmy3tables).
