Popular Post stevel Posted January 16, 2023 Popular Post Share Posted January 16, 2023 I have been drawing and printing, my design now for a year or so and, for my planned layout of the Falmouth branch, set in the year 1908. I have chosen the period and location, because of two requirements, I wanted a Brunel viaduct or two, and wanted to model the Edwardian period, with a strong tie to real locations. After many years away form the hobby, I realised most of what was required for the period and location was not available from current suppliers, so decided it was either scratch build, or draw them in Fusion 360, and then 3d print them. The attached image is a small sample of what I have done up to the present day. Prints are from the Anycubic mono SE or the recently acquired Mono X, which gives me the ability to print bogie coaches up to 54ft. 16 10 1 Link to post Share on other sites More sharing options...
drduncan Posted January 16, 2023 Share Posted January 16, 2023 Great to see your work. Any chance you could post images of the 1 plank single shoe brake gear? I've yet to find a good image on which to base such a version of my 1 plank 17'6 and 18' wagons - which are the only ones I've found in the wagon stock books that have single shoe brakes (and not many of them at that). Most of the other 1 planks up to and including the 17'6 ones use double shoe brakes either 9ft or 10ft wheelbase and thanks to (I think) @Compound2632 I found a wooden double show drawing which I stretched to make a 10ft version. On my BG fish wagons I've had some success using 0.3mm brass rod for the axle tie rods which avoids the wavy 3d print issue. Look forward to seeing more of your excellent work soon. Regards, Duncan 1 1 Link to post Share on other sites More sharing options...

Regards, Duncan I based the single brake block wagon, on the picture from, a history of GWR goods wagons Vol1. Scanned image attached. The axle tie rods waviness is caused by a slight horizontal warping of the wagon, as they were tight originally, But for future 6 wheelers I will be going with etched w-irons, as my experiments with a floating centre axle have not work so far. 2 1 1 Link to post Share on other sites More sharing options...
stevel Posted January 17, 2023 Author Share Posted January 17, 2023 (edited) One of the first pieces I drew and printed was the AA16, wood framed brake wagon. This is the second attempt as the first had too many errors. Printed in the translucent green makes it hard to see the detail, and it took more than a dozen prints, with small detail changes before I was happy with it.

Schooner Posted January 17, 2023 Share Posted January 17, 2023 That's the first time I've started following a thread after reading the first sentence alone! Sounds - and looks - an excellent project, interested to see how it develops. How much of the branch are you planning to model? A Brunel viaduct 'or two' suggests that it's going to be some bleddy thing, as they say in Falmouth. Good luck! 1 1 Link to post Share on other sites More sharing options...

I am hoping to build a wood workshop, which will have a loft above, with about 9m x 5m of space, with the intention of modelling Penryn, and Peranwell. 1 1 Link to post Share on other sites More sharing options...
stevel Posted January 22, 2023 Author Share Posted January 22, 2023 I thought it may of interest, to show some of the steps, to draw in Fusion 360, and then print a model wagon. The model chosen is of the GWR 021, 4 plank with grease axle boxes. the first stage with something that is symetrical, is to draw one quarter of the wagon. then the pre drawn components, in this case, the W-iron with the axle box and springs, are brought in and moved to the correct location. the next component to be added is the buffer body. Once all the details are in place it is time to mirror the model, to get the complete wagon model. first mirror get a half wagon, and the second mirror gets the complete wagon. At this stage the single side brake set up can be drawn and extruded. The final stage for me, is to add on the sacrificial supports, to ensure a clean edged print. 4 3 3 1 Link to post Share on other sites More sharing options...

Iiiiideal :) The former was my local for a spell, looking forward to seeing it develop in model form. Much nicer than in modern form, although it can lay claim to being one of very few stations with an interesting traffic pattern! 1 Link to post Share on other sites More sharing options...
stevel Posted January 22, 2023 Author Share Posted January 22, 2023 I have been surprised, at how little information available for the Falmouth branch, I have bought every railway book I can find that even mentions it with not much luck. Link to post Share on other sites More sharing options...
stevel Posted January 23, 2023 Author Share Posted January 23, 2023 Here is the next stage of the process, the printing. the left hand model is the first print, using Anycubic grey without the sacrificial ribs. The print has warped along the top edges quite a bit, and some of the supports have broken away causing other issues. The middle is the same resin with the ribs, but still has some warping issues. Th right hand side model is printed using the Siraya tech mix, and has come out very clean and crisp, with no top edge warping. All of these were printed in warmed enclosures, Both using factory settings. here are the second and third prints, with supports, note the warping of the rib support where the supports have pulled away. the third print with a light black primer base. 8 1 1 Link to post Share on other sites More sharing options...
Schooner Posted January 23, 2023 Share Posted January 23, 2023 Re sources, just checking you've come across these map libraries? Usually I would recommend Britain From Above as well, but there's only one useful photo. Link to post Share on other sites More sharing options...

Usually I would recommend Britain From Above as well, but there's only one useful photo. I have spent many an hour pouring over them, a very useful resource. So many lesser branches have had great books written about them, but not the Falmouth branch. Found some very interesting info on the web, but there are a lot of views, such as the cattle dock, the broad gauge coach body, etc I cannot find. The Britain from above is an interesting period picture, thanks. Stephen Link to post Share on other sites More sharing options...
RMweb Gold 57xx Posted January 25, 2023 RMweb Gold Share Posted January 25, 2023 I'd be interested to know more about the 20T loco col wagon. Is it an N2? Link to post Share on other sites More sharing options...

Is it an N2? you are correct sir, a tricky little beggar to draw, and took few test prints and revisions to get right. Here are a couple more pics. 4 Link to post Share on other sites More sharing options...
stevel Posted February 5, 2023 Author Share Posted February 5, 2023 Something else I am working on at present is the G20 Dean 6 wheel Saloon, like the one they have restored at Didcot. I am having an issue trying to figure out what the spring centres are. from hanger to hanger, as the pictures, and the drawings I have don't show it. here is the progress so far. This will be mounted on MJT/Dart 3 axle floating w-irons, once they get here. 8 Link to post Share on other sites More sharing options...
drduncan Posted February 6, 2023 Share Posted February 6, 2023 They used 6ft springs with j hangers, I think. The model looks very good. Duncan 1 Link to post Share on other sites More sharing options...
drduncan Posted February 6, 2023 Share Posted February 6, 2023 If you used 6ft springs on your Tadpole you could alter it and the j hanger assembly to be a separate body and cut/paste it across in Fusion or turn it into a component which can then be used across designs.

Duncan I was hoping it was 6ft as I have it as a component, I have been doing more and more component drawings, to speed things up and cut down on redrawing every time. 1 1 Link to post Share on other sites More sharing options...

There were 48 built in total, under 5 lots. all were condemned by 1939, with three converted for other uses.
