The Foundry Process 

Robert Clolery beggar!

No and no. The mold was stood on end.

See the big Culverin cannons recovered from the 1545 Mary Rose shipwreck, the Iron cannons at least were forged from flat iron bars, that's why they have an outer Hexagon shape Composite cannons with forged iron barrel liners & Bronze outer casings have been around since at least the 16th century described in historical accounts, the oldest physical example is one recovered from the 1629 Batavia shipwreck off the Western coast of Australia The Maratha and Rajput mughals manufactured composite cannons in the 18th century as did the Chinese. These types of cannon were far lighter & stronger than cast iron or bronze cannon, however the difficulty in manufacture meant they were never widely adopted. Here's a link to a 2005 scientific study of a Mughal iron / bronze composite cannon. insa.nic.in/writereaddata/UpLoadedFiles/IJHS/Vol3_2005_08_AZDAHA%20PAIKAR%20THE%20COMPOSITE%20IRON%20BROZE%20CANNON%20AT%20MUSA%20BURJ%20OF%20GOLCONDA%20FORT.pdf

Original proof loads were double the maximum field loading of powder for the canon as well as two cannon balls. If it fired without exploding or damage to the cannon, it passed lol.

Contact South Bend Replicas for a price on a good one.

They can be from 25 to 60 thousand dollars.

I've seen 2 1/4" bore cannons with a carriage for $2,000 and with targets that prove it shoots. I don't believe that SBR puts the sleeve in before pouring. They drill and machine the iron and press the steel tube into the bore. Then it's secured in such a way that it will not go down range during a firing. I would never trust wielded trunions.

It's better than the original but the design is the same

@@HostileLemons right. so why not make a stainless steel one. just like what your saying 'its better than the original but the design is the same.

@JCElzinga: Stainless steel alloys wouldn't be suitable to make good canon; they'd either be weaker or potentially more brittle and explode. Ductile iron is the toughest, safest metallurgical option. Because stainless doesn't rust, it doesn't mean it's stronger. Also, despite this being an excellent documentary, quite a bit wasn't mentioned, such as the grade and type of steel tube used for the bore, and what grade of ductile iron the casting was, not to mention any possible heat treatment processes applied later for the purpose of metallurgical stability. It would be interesting to know, but not in the commercial interests of the company to divulge, I guess.

@@zhouzhang9102 good call on the stainless, but maybe missing the point of, is it really reproduction? like if you make me an english warbow with carbon fiber is that really 'reproduction' how faithful to the original do you have to be to be considered reproduction? a question for philosophers. I was hoping for a 'this is how they did it' kind of documentary.

@@JCElzinga I'll make an exact replica for you. It comes with everything period correct, including the possibility of bursting in your stupid face.

Abdul, take your Haji butt back home!

Jesus would be proud of how you are such a good reflection of the love for ALL mankind he taught. I'm guessing by your ignorance you're American... Funny you don't look indigenous native in your pic, How bout you go home? Also youtube isn't U.S. only, WWW stands for World Wide Web.

@@tatumergo3931 you're funny.

too much compared to were I work haha
