Having not seen nearly enough artillery models built I thought I would post a picture of my first model. Its a fairly simple scale model of a 10 inch Mortar from the Victorian era. If anyone is interested I can put up a few more pics as it progresses.

Is anyone else building this kind of thing?

Thanks.img_5200.jpgimg_5201.jpg

My very first engineering model was of a 12 pounder naval cannon as carried on Victory from the plans in Longridges' " The Anatomy of Nelsons Ships".

The inspection department where I worked had a Boxford lathe that I was allowed to use at lunchtimes, the company also made bespoke kitchens so there was some nice wood to make the carriage and the aerospace department heat treatment ovens provided a nice blued finish.

The cannon is still in my workshop.

Well, I made this 1:10 scale C18 24-pounder from plans by he late Jerry Howell of the USA.cimg0024.jpg

I had a go at anglicising the more obvious American design aspects, Looking at Muller's 'Treatise Of Artillery' from 1791 I noticed a number of differences that I suspect are inaccurate simpifications, but it still looks OK on the windowsill.

I would like to make something more modern, but haven't yet found any suitable drawings.

I have a project in mind [in the back of my mind ] to make a cannon gun on wheels,to grace my front lawn,perhaps about 3/4 full size.,something about late 1700/early 1800.

Still thinking Any ideas ?

Richard,

That's a very nice model. I'd be very interested in more photos showing how the bed goes together and how you made/fitted the fillets next to the trunnions, these look very neat in the photos.

I am part way through a build of a 1;16 scale model of a 13 inch Victorian era land service mortar which will utilise a slightly later design of bed than yours. It's in brass as it's just a mantelpiece project (non-firing):-

Mick - I like your Jerry Howell cannon. I found the drawings to be pretty good, although I can't comment on their accuracy/authenticity. Here's my version at 1:20 scale:-

Many thanks, I like your models a lot too.
The bed was drawn on autocad and is made of 8 pieces of steel. I then sent the files to Malcolm at ME Laser who cut them for me. I then tig welded it all together. It was the only way I could think of other than screwing them together which seemed a lot more work. As I was painting this model black I was not too concerned about using welds.

The fillets were a real pain in the bum. As you know they have curves in awkward directions and seemed to me to be impossible to machine so I filed them. I first bored the hole for the trunnion into the fillet. I then pushed blutac onto the barrel and made a blutac filet. After carefully taking this off it gave me the shape I needed to file. It was very tricky but I did get a half decent fit in the end. They were then attached with an epoxy metal from b and q and a small amount was needed to fill some small gaps. I doubt this would be any good for you though as you are probably not intending to paint your brass model but I am going to paint mine.

If you do find a way let me know, I can only think of casting a complete barrel but thats not much help.

Regards

Rich

Hi Rich,

Thanks for the additional photos. I'd like to see a photo or two when it's finished and painted. I intend to screw the parts of the bed together on mine. I am sure there must be a way to machine the fillets for the trunnions - I just haven't figured out how just yet!

How will he clean up the bit of barrel between the trunnions and get it as nice as the turned bits at either end?

Very good question, to which I don’t know the answer. I’ve contemplated building a civil war canon before and always wanted to construct the trunnions properly but this is one of the aspects that put me off the project!

An update on the mortar, its now finished so I have uploaded a few photos. I hope you like it!

Next will hopefully be a Victorian Rifled Muzzle Loader on a pivoting carriage.

Excellent job Richard. Where was the picture of the original taken? Looking forward to some pics of your RML.

Can I suggest you look on http://archive.org and do a search for the 6" MkXII Naval gun manual from 1917. They have a handbook for the gun and gizmos, with drawings at the end of the book of both the barrel and gubbins. Only the barrel is dimensioned, though.

Thanks for that. It looks a big project - investigating later...laugh

I got the picture from a google search I think it is Fort Henry in Ontario. I have actually only seen these mortars twice. One was in the army museum in Lisbon and one in Guernsey. The drawings I made were from scaling various photos from google. There are so many different variations of the same piece that its difficult to make an exact scale model unless you visit one with a tape measure. That's why the grey block looks different as I would have copied that from a different picture.

Thanks

Rich
