Rob Pulham Posted October 20, 2022 Share Posted October 20, 2022 (edited) Hi All, This thread is to detail my semi scratch build of a Mark I Gun Carriage. It's to be used primarily as a load for a train of armour at some future point when I have enough vehicles and loads to actually make up some kind of train. I say semi scratch build because although I have completely scratch built a few railway related items I also make use of a Silhouette Cutter and more recently 3D drawing (I don't have a printer but I have a friend who does) and a workshop equipped with a lathe, Milling machine and Guillotine. Even though it will be a wagon load, I will be adding lot's for detail as that's where I get my pleasure. I would like to offer my public thanks Model Mate of this parish for sharing the info that he has collected for his scratch build of the MKI Gun Carrier with a new member who at that point hadn't even made a single post. It was reading his excellent thread on the subject that inspired me to have a go. Anyway enough of the waffle, last night I made a small start and based on one of the plans that MM shared I drew up the wheels for the howitzer.

Model Mate Posted October 20, 2022 Share Posted October 20, 2022 excellent start Rob - and good to see the more obscure subjects getting some attention.... there'll soon be as many Mk1's as Shermans here! 1 Link to comment Share on other sites More sharing options...

Rob Pulham Posted October 20, 2022 Author Share Posted October 20, 2022 While I was in the 3D drawing zone I also drew a 2 gallon POW can and a Jerry can. Admittedly the latter is not much use for WWI armour but it was an interesting exercise. I did simplify the locking cap because I doubled it would print successfully with the full locking mechanism. I do appreciate that you can buy these as aftermarket accessories but the tight Yorkshireman makes me want to do them as cheap as poss... 4 Link to comment Share on other sites More sharing options...
ColonelKrypton Posted October 20, 2022 Share Posted October 20, 2022 Rob, Very nice start to your scratch build project. It will be interesting to watch your project come to life. cheers, Graham 1 Link to comment Share on other sites More sharing options...
Rob Pulham Posted October 25, 2022 Author Share Posted October 25, 2022 Not much in the way of further progress at the minute, I am trying to get my head around the best way to rescale the Landships pdfs consistently from 1:48 to 1:43. So far my brain tells me that logically 1:43 is bigger but my dodgy maths keeps getting it smaller... Link to comment Share on other sites More sharing options...
ColonelKrypton Posted October 25, 2022 Share Posted October 25, 2022 multiply by 48/43 or 111.6279 % ( 1.116279 x larger ) cheers, Graham 1 1 Link to comment Share on other sites More sharing options...
Rob Pulham Posted October 25, 2022 Author Share Posted October 25, 2022 Cheers Graham, As you might expect lots of things ding conversions out on the web but nothing that I found which tells you how it arrives at the figure. Thanks again 1 Link to comment Share on other sites More sharing options...

Do you mean cans like these? 1 Link to comment Share on other sites More sharing options...
Rob Pulham Posted October 26, 2022 Author Share Posted October 26, 2022 Almost Pete, it looks like we have been reinventing the wheel. Yours I have to say are much nicer than mine. How do you find locking mechanism prints? I may revise mine. Can I also ask what font you used for the text on the 2 gallon can? Many thanks for sharing them. 1 Link to comment Share on other sites More sharing options...
PeteH1969 Posted October 26, 2022 Share Posted October 26, 2022 They print really well @ .030 layer height all the detail is there orientated vertically they take a while but worth it. Having the real cans to model from make it so much easier. Pete 1 Link to comment Share on other sites More sharing options...

Pete I bet it does, I struggled to get the basic dimensions. The spout/cap on the 2 gallon can is best guess. 1 Link to comment Share on other sites More sharing options...
Rob Pulham Posted November 4, 2022 Author Share Posted November 4, 2022 I had a spare half hour this afternoon so I started to draw out/sketch over the gun carrier lower hull sections. I started by outlining the lower sketch of the inner side first and then duplicated it for the outer side. All was fine until I moved it up over the sketch for the outer side. They are different. I wonder if this is by accident or design? 4 Link to comment Share on other sites More sharing options...
Rob Pulham Posted November 4, 2022 Author Share Posted November 4, 2022 A further look this evening and I worked out what was wrong. the upper/outer hull sketch has the part reversed. As soon as I flip it it fits as it should phew! 4 Link to comment Share on other sites More sharing options...
Rob Pulham Posted November 13, 2022 Author Share Posted November 13, 2022 I am still beavering away drawing up the parts for the lower hull. I had a bit of hope when I read an article about drawing in Fusion 360 and then exporting as an SVG file which I could use on my silhouette cutter. Sadly the hope came to nothing and I have gone back to drawing it in Inkscape. It's been a while since I have used it and it seems quite primitive now that I am used to Fusion but we are where we are. So far I have the basic shape, and the inner and outer rivet strips. The Silhouette will cut an impression of the rivets which are quite convincing. If you enlarge this image and look at the rivets on the tank you will see what I mean. 3 Link to comment Share on other sites More sharing options...
Peter2 Posted November 14, 2022 Share Posted November 14, 2022 Nice detailing and drawing. Can I ask why you chose a scale of 1/43? For example 1/35 scale might provide more "spare parts" and accessories such as fuel cans, helmets, crates and so on to complement your scratchbuilding; as well as personnel to accompany the model.

Rob Pulham Posted November 14, 2022 Author Share Posted November 14, 2022 Hi Peter, Thanks for looking in. Why 1:43? It's because I intend to have this particular build, to be a load for a railway wagon (I am primarily a 7mm/1:43 scale railway modeller) I also have a brass kit for a MKIV Tank and a Rectank wagon. That said I do seem to be acquiring 1:35 kits too. Besides the Tamiya Panther that I am building on another thread I have a Warslug Rolls Royce AC waiting in the wings for Christmas to arrive. In the future I may well do other WWI AC scratch builds and I am undecided as to which scale to do them at the minute, lets see how this one turns out.

Model Mate Posted November 14, 2022 Share Posted November 14, 2022 ....I can confirm that at 1:35, it's massive as well, so 1:43 (although a bit odd for us armour types) is a sensible approach! Looking great so far Rob. I use Microstation (CAD/BIM software) a lot professionally, so that was my drawing/tracing software of choice, and didn't take too long to draw it all out. I could send you pdfs of my sheets if that would help? Link to comment Share on other sites More sharing options...
Rob Pulham Posted November 14, 2022 Author Share Posted November 14, 2022 Despite 20 years in IT I haven't heard of Microstation Yes please to the pdf's, every little helps as they say. Many thanks Link to comment Share on other sites More sharing options...
Rob Pulham Posted December 3, 2022 Author Share Posted December 3, 2022 This project received a much needed boost in the form of some 3D printed wheels and stowage type items from the friend who does my printing. Howitzer wheels 2 Gallon POW cans 2 Gallon Petrol Cans Thanks must go to @PeteH1969 for his assistance with some of these items. 4 Link to comment Share on other sites More sharing options...
