Another Model Cannon?
by John
I had thought that the 1:10 scale model Armstrong 80pr rifled muzzle loader would be the last cannon which I would make. It is currently being given finishing coatings to the woodwork. Later this year it will be given as a gift to a family member.
To be honest, having made five 1:10 scale model blackpowder cannons, I am ready to move back to my first modelling passion, which is steam engines. I had no real interest in weapons or guns or artillery, except as a means of increasing my understanding of history, specifically military history. I have no interest in firing guns, although I must admit to an illicit satisfaction in watching You Tube videos from USA of cannon modellers who can actually fire their creations.
My interest in cannons started when, as a newbie in CNC machining, and looking around for a project to use my newly acquired CNC lathe in 2015, I made a model long gun.




And the most recent Rifled Muzzle loader, the same 80pr Armstrong Barrel, on a Dwarf carriage, and wooden traversing platform.

I truly thought that this would be the final cannon which I would model. So I could get back to my model steam engines.
Like this one from 2-3 years ago, now gracing our kitchen, with decorations by SWMBO.

BUT….then my eldest daughter, who has absolutely NO interest in cannons, asked ” are you going to make a cannon for me?” I must point out that this daughter rescues injured animals and takes them to her vet, is vegan, the most pacifistic and socially conscious person that I know. I questioned why she would want a model cannon. “I just do” she replied.
Oh well. I guess that I will be making one final model cannon.
I spent a day searching my books, Google Images, Wikipedia for a cannon which would look interesting as a model, be interesting for me to make, and for which some plans or drawings are available. I offered my daughter the choice of my existing models, but no, she wanted one built just for her.
Then I thought of jefenry, my reader from the USA, who has made several model cannons, including one which intrigued me when I first saw his pictures and videos several years ago. It is a 1:9 scale Armstrong rifled breech loader, 110pr, of 1861. One of the first breech loaders of relatively modern times. (Breech loading cannons have been around since medieval times, but they were less reliable than muzzle loaders, more inclined to explode and kill their own gunners.). The Armstrong 110 pr RBL saw action in several wars, including against Japan, the NZ Maoris. It was the largest cannon on HMS Warrior, but was replaced by the more reliable muzzle loaders.
So that is what I will model for my daughter. An Armstrong 110pr, rifled breech loader, on a dwarf carriage and wooden traversing carriage. Here are some pictures.


So, my plan is to make a 1:10 model of the barrel, on a carriage and traversing platform like the Fort Henry example above. Not sure how much of the build will be featured on this blog. I am again very close to my WordPress.com memory limit.
Hi John
Have you checked Home Model Engine Machinist Forum I love this site. You can post all your projects as they progress and there is a wealth of great project happening all the time.
Have a look
Cheers
John

Good idea John. I am getting a bit fed up with WordPress.

Nice! I’m glad my cannon was an inspiration and I’m looking forward to seeing how yours turns out. I’ve got a folder full of documentation I collected when I was making my model. If you think it would help I could stick it on my website and you could download it. Mostly reference pictures, drawings, and old manuals.

Jeff, that would be greatly appreciated. I am still collecting as much info as I can, including the progressive photos on your website. Still wondering how I will attach the trunnions. I think that you welded them to trunnion ring, then shrunk the ring to the barrel. Is that what you would still recommend? (if so, how did you clean up the weld?). Any info would be excellent. john.

Jeff, THANKYOU! Fantastic info and photos. Particularly excited by the photos of the original Smith’s elevating screw, which I can see is left handed!
(where is it located??) Today I bought some 76mm 1020 steel, and I can’t wait to start machining. Still not decided about the trunnion ring. Who knows? I might just need the strongest option. I am now thinking of making a 110pr for myself as well as my daughter. My email is jviggers@iinet.net.au if you think more private communication is preferable. I have downloaded your files to 2 computers so I do not lose it in some disaster. OK to delete whenever. Thanks again. Do call in if you ever find yourself downunder. John V.
