SR Brighton Steam, 3D Printed in OO

Recommended Posts

Hello fellow modellers, designers and printerers!

 

This is my first post onto this forum (or any!) after much prompting by my good friend Jack P - please visit his workbench as he has been key to my railway modelling revival so I can't thank him enough.

 

So the story goes that I discovered the joys and wonders of CAD a few years ago while at uni, which led me to the 3D printing laboratory and from that point I got hooked on the process. Day and night was spent there, until one day I decided to have a crack at a loco. I was lucky enough to have access to a FormLabs Form 2, and thus the SECR J was the first to come off the printer. Having designed it on an old Airfix Prairie chassis and off eyeballing online pictures only, the proportions are all over the shop and especially due to the giant motor, topped off by my appalling paintwork......

I thought I could do better than that so I had a look at some other prototypes and the LBSCR K had always stood out, so I had a go at that. The large parts were done on an Ultimaker 3 with the detail again on the Form. The Airfix Prairie chassis was chosen once again and seemed to suit an awful lot better! But the paintwork needed some better skills, which is where Jack P joined the party and finished it off for me - the alliance was born! He's done an amazing job as you can see below.

So what's next on the list? There is a LBSCR J1 on a custom 3D printed chassis at the ready-to-print stage, hoping this can be printed fully in resin somehow. Also I have started work on the LBSCR Director's Saloon (as on the Bluebell) in its SR modified state with gangways (screens of both to follow!). I'm again hoping for full resin but its still in its infancy, particularly because uni is now a thing of the past so no more free printing, and I do CAD for a living for the big railway so I tend to favour other things in my free time. But slow progress is better than no progress - I have a small list of other prototypes I would like to have a crack at currently standing in no particular order at:

 

A better LBSCR K,

LBSCR B4x

LBSCR D3

LBSCR C2x

LSWR H16

Some other stuff?

 

So the big questions to the crowd and for this relative newbie: how does one go about finding resources to produce accurate CAD models? Where does one find reliable GAs? Also, are people interested in these models for themselves, in some form or another?

 

The project taking up all my time is in fact a DC electronic signalling system, which can protect blocks, operate signals, read points, ramp up and down the speed range accordingly, all automatically into one PCB (per signal that is). Spurred on by another friends' building of a layout I thought this needs some investigation. I have a proven working custom IR track sensor in hand, and initial simulation testing is promising - I have some good confidence it could work so far! Might I need a separate thread for this? Do you think this is a practical system, given some vast wiring required too?

 

Anyway that's my introduction, thanks for your time and I look forward to hearing some thoughts!

Welcome aboard - very interesting what you are doing - I'm sure you will find an audience for your work.

BB, Is it your intention to market these to the public? I had followed the 'K' on Jack P's thread and it looks very good. I am at present trying to revive a 30-odd y.o. kit-build of a K's K, your print looks very good in comparison.

cheers from Oz,

Peter C.

Going to be following with interest. I could be after a K and a C2X double dome....... Backnumbers of Railway Modeller could produce scale drawings. I don't know the issues but know doubt others on here will.

Very impressive for first efforts. For drawings you could use back issues of a number of model railway mags such as RM (as above) and Model Railway Constructor. As you seem to be favouring Southern prototypes keep a look out for J H Russell's 'A Pictorial Record of Southern Locomotives'.

I shall be following with a lot of interest!

 

Regarding drawings, I can probably rustle up a D3 for you. That said, Golden Arrow do a very good one of these already.

 

As for the H16, any chance of doing a version for a Hornby S15 chassis? I have one of these set aside already and intended doing my own CAD for it.

Hi BrightonBoi, what CAD package do you use for your drawings?   A very effective way of getting the engines you desire :good_mini: please keep it up (I'll be following progress with interest)

Great to see such a positive reception so far! I'll have a look out for some of those books, seems like a favoured resource.

 

I am hoping to release some of these designs to the public at some point long-term but I know little about how to go about that. So far I know that ShapeWays is incredibly expensive, open-source requires people to have their own printers, so what's left? Perhaps a look at other companies, or even buy a printer and operate a business out of my bedroom! I'm certainly up for suggestions in this area.

As Jack has rightly pointed out, I had exactly the same idea! Building on an existing chassis does seem to be easier, but my major stumbling block with the H16 is correcting the expansion link bracket. The S15 chassis holds the motion up with some tiny plastic push-fit sleeves, so without gluing it to the new bracket it needs some thought.

 

I would absolutely appreciate some D3 drawings if you are happy to supply them, thank you. It may go up in the pile if so....

Short answer is, it depends :lol: I seem to be jumping between convenient licences: I started out in SolidWorks for the SECR J and K, moved to Fusion for the LBSCR J and the start of the Saloon, but after cloud issues I'm considering going to my work's package - Inventor. So that's up for debate.... Talking of the LBSCR J, here are some screens of it below. The Saloon will come when Fusion starts behaving :wacko:

The cab is a grey area, it was taken from a blurry image of a drawing of an L class cab, bodged into my K, and then into this J. I don't think there's anything accurate left in it! But Jack came up trumps and found some GAs of the outside so that's pretty good.

 

Enjoy! Thanks for the support so far.

I have 1000's of Drawings, if you get stuck let me know what you are after. I have them all in Solidworks 2019 , AutoCAD 2019, Inventor, Fusion 360, DWG, DXF, PDF Format (Sorry my hobby is CAD lol, Hence I have so many)

 

Cheers :)

Hi Brighton Boi , loving your work so far ,especially the H16 to fit the  Hornby s15 chassis . Regarding  drawings , as well as  trainmad 98, there was a small booklet published  by a chap called LeLeux  sometime  ago listing all the drawings of locos, wagons, coaches  & all assorted railway items ,such as bridges,goods sheds, etc   in the pre 2000 model railway magazines- many of which I have  & will supply you with copies  if I have them. 

Keep up the Great work

Ive been very fortunate to be able to print the J1 by @BrightonBoi as part of one of his first works.

 

An overall excellent model by him! I cant wait to see what he comes out with in the future!

 

Cheers!

Hi  Javier,I would be really interested  in as example  as well, if possible  and  what is the other loco  in the background?

Hi Paul, I wouldnt wish to steal BrightonBoi's thunder on his blog. Its an I3 by me that was part of the same order.

 

Best
