Another Model Cannon?

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.

1:10 scale models of a 1779 24 pounder long gun, and 1804 carronade of the same bore. Making them was interesting, and the associated history was totally engrossing.
Then the Ottoman cannon of 1465, again 1:10 scale, over 500mm long.

The Armstrong 80pr muzzle loader, scaled from the originals at Port Fairy and Warrnambool.
Another Armstrong RML 80pr. I kept this one.

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

Almost but not quite completely finished in this photo. Since then it has been cleaned, stained, and lacquered.

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.

Trevithick dredger engine and boiler, of about 1805. 1:8 scale. The possum and the budgerigar are not real. Neither are the two T. Rex’s fighting on the boiler.

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.

110pr Armstrong at Fort Henry, Canada. I presume that the traversing carriage is a reconstruction.
And the 1:9 model of a naval version of the gun, which was made by jefenry. Check out the making of the cannon, including rifling, at jefenry.com and watch his video of firing the cannon at https://youtu.be/m3pC0eDvs90

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.

Well, what a nice day!

Wednesday is always a good day.  That is when our model engineering group has its weekly meetings.  Mostly a 2-3 hour informal gathering around a large table, chatting about current projects, new tools, the weather, rarely politics or religion.  Coffee.   And once each month a more formal evening meeting, involving discussion of club business, “models on the table” and usually a guest speaker.   Today was the informal 2-3 hour chat variety.

I used the opportunity to ask about methods of making a rectangularish water tank for the Trevithick dredger engine, riveting, folding brass, caulking with solder, etc etc.    And Stuart T, knowing that I had to make a stainless steel compression spring for the safety valve of the Trevithick, brought in his tools for making springs.

This is one of the tools.  It was designed by Dwight Giles, and made by Stuart.

Published in Model Engine Builder 2007.

The tool is mounted in the lathe tool post.  The V supports the chuck mounted mandrel, and the brass washers apply drag to the spring wire.  The lathe threading gears supply the pitch to the spring.  Looks excellent, and I was hoping that Stuart was intending to lend it to me.  Otherwise I would make one of these tools.   But why were there two of the tools?   “Oh, one is for you!  I was making one for myself, and it was just as easy to make two.”

Not the first time have I been the recipient of Stuart’s generosity.  When I make the spring (soon) I will take some pics, and post them here.

Later in the meeting, Swen Pettig, recently returned from a fabulous trip to Scandinavia and UK, called for shoosh, and stood up to make a presentation.  Some people knew what was coming.  I didn’t.  But in “recognition for writing about his model making” (now my ears pricked up), Swen had picked up an item in the UK which he thought I might find interesting.  Knowing of my current interest, some might say obsession, with Richard Trevithick, he had looked for and found the following item.

A Two pound coin.  I did not get the significance, until I looked more closely.  Holy Shit!  That is a Trevithick engine on the coin.  The Pen-y-Darren railway engine if I am not mistaken.  Made in 1804.  And using many recognisable features which are in my slightly later dredger engine.  The coin was minted in 2004, 200 years later.  Wow!!

I did not even know about the coin until today.  But I am honoured and very grateful for this lovely gift and thought, Swen.

One wag suggested that I should make another gas knob for the engine, and mount the coin in the knob. (thankyou for the suggestion, President Brendan.  I will do no such thing).  It will be a  valued possession.

Incidentally, the reverse of the coin has an image of the Head of State of Australia.

Bye Bye

WordPress has increased their annual fees by another 30%.  under the guise of a “domain name” fee.

Sorry guys and gals, but I am not wearing it.

Thankyou for following.  And a big thank you  for those who have commented or liked my posts.

But I am not forking out another 30% per year, on top of a similar increase a year or so ago.  They are just, fucking, greedy.  too expensive.


.

So bye!    ….John.

p.s.  when the Trevithick dredger engine is running on steam I will post a video on YouTube and maybe Facebook.

pps.  If you want to visit old johnsmachines.com posts, I believe that you will be able to open them by including “wordpress” before the johnsmachines.com

ppps.  if you think that this stinks, don’t tell me.  Tell WordPress.

pppps.  my email is jviggers@iinet.net.au
