After seeing other playing with 3D printing I though I would have a go. I have had a go at making a Metropolitan 1906 Bo-Bo from some drawings. It is in OO gauge and is just a body so requires a chassis and motor to get running. Any feedback would be greatly appreciated as I would like to check it is right before I order one for myself and try to turn it into a working model. www.shapeways.com/model/683420/met-1906-loco.html?li=cart&materialId=6 |

Looks really good! Perhaps you can use the Radley Models chasis with some mods? You could of course make your own from plasticard. Just make sure it uses thick card with deeper sections to give it strength.
The bogies could be the T stock type with some mods, but the 7'9'' wheel base is about right. Remember these locos received new bogies in 1913-14 when new saloon stock motor cars were built and took these locos' BTH motors and bogies!

For a chassis I would suggest using an HO scale American 'switcher' chassis as the dimensions will be very close to what you want. These locomotives had a bogie wheelbase of 7' 6" with bogie centres of 17 feet. Most American switchers have 8' 6" bogies with the centres at 19'. In 4 mm scale this works out at 30 mm and 68 mm respectively. The switcher chassis (in HO scale) works out at 29.75 mm and 66.5 mm respectively.

It certainly has the right 'look' to it - will look forwards to seeing more.

What's particularly good is that the ribbing is not at all clumsy ( a common fault even in G scale, let alone OO)

It looks good, northfields. I assume you are printing in Fine Ultra Detail? It is more expensive, but worth the extra$$$ because the crispness of detail is preserved in the printout. Look forward to seeing the final model. ( www.shapeways.com/shops/The%20Forth%20Rail ) |

Thanks for the comments.
Metman-I have looked on the Radley Models Website and they only appear to sell bodies and bogies spare. Is there a way of getting the chassis separately as a spare as I can't seem to find it on their website?
Phillw48-Thanks for the advice and I will probably get a switcher chassis as it will make it easier to fit DCC which I use as it is DCC ready. I assume this has been used for other metropolitan locos such as the "Sarah Siddons" Type Bo-Bo or has it been used by other people who made 1906 locos?
Cyberman-I was not thinking I needed to use ultra detail as I was trying to keep costs down so thought strong and flexible would work but I am reconsidering now. Its a pity they cannot be the cost of resin bodies from places like radley models but I guess that is because they have a master that they have made moulds from not a custom 3D print like what I am trying to do.

Northfields-it you send Phil Radley an email he should be able to sort you out with just the chasis. He's certainly sorted me spare and the like for my little projects in the past.
Depending on how many coaches you are going to pull (Dreadnoughts?) you may want to insert two linked black beetles into the chasis which is what I am going to do when I build my Met electric locos. I believe the RM kit is designed to accept BBs but I don't have one to prove it!
Best of luck.

northfields, I would recommend using the FUD. It is extra $$$, but the results are worth it, certainly after the investment in time of making the drawing along with details and getting everything right. Good luck for 2013!

Thanks very much for all the advice I have been given so far.
I have made my model based on a diagram of the loco and one photograph I found in "London Transport Railways Album" By Chris Heaps.
I have however realised that I know near to nothing about the loco as the book only has 2 sentences on the class. If anyone has any information about the class then I would be grateful for it. I need all the information I can get my hands on to be sure my model is right as I realised I made a few educated guesses when designing the model and would like to check whether they are right.

Bill Simpson's 'A History of the Metropolitan Railway Vol 1' has a couple of pics so at least one must be different from what you've seen. P59 and P144
Sorry I can't copy them as it's not my copyright.

P59 and P144 Sorry I can't copy them as it's not my copyright. There's another on P.73 as well. Fyi there doesn't seem to be much text about them, just a list of the locos 11-20 on P.144 with the pic. |

There will be some photos I'm sure on the LTM site...
Edit: Actually I can't find anything.....

If you can still find a copy, Besnet's book "Metropolitan Railway Electric Locomotives (LURS 1983) has a lot of views of that batch of locos. Maybe evilbay beckons...?

The BWE locos 1-10 had a body length of 30'9'', bogie centres at 17'3'' and overall length from the buffers 35'9''. The BTH locos 11-20 had a body length of 30'0'', bogie centres at 17'0'' and overall length from the buffers 33'6''. Their height was 12'3 7/8'' and width 8'0'' (panels) 8'7''. Body started 4'0 3/8'' from the railhead. The Radley models chasis would be a good basis for this model although the bogies are wrong. Use F stock bogies for the old BTH type (7'6'') or T stock bogies for the 1913 replacements (7'9''). I hope this helps. For more info PM me  |

The project is progressing slowly but surely. After receiving some parts from radley models I realised that they did not do a similar enough chassis so I would design my own copying their basic design of chassis so their F Stock bogies could be used. I have also acquired a copy of Ian Huntleys Surface Stock Planbook which has been invaluable. Following this I have modified the cab windows and handrails as I had got these wrong(I have copied the style of the radley models handrail provisions also). All I need to do now is to finish adding detail to the chassis, though I will use ready made buffers and maybe other components to make things easier for myself. The shapeways page( www.shapeways.com/model/683420/met-1906-loco.html) has been updated so you can see progress, and I have also left the picture of the original model so you can compare how it has evolved. I hope to be able to get it printed soon and I will let you know as things happen. |

It's coming along nicely. Thankfully most of the equipment is in the body so you don't need at add too much to the chasis.
Your chasis looks good. Can you not adapt it for the F stock bogies? I assume you will be using one or two motor bogies? How many coaches are you attempting to pull?

Metman- I have use measurements from the radley models chassis to design mine to make it in the same style. I have hence used the same size holes for mounting bogies so they should be compatible, I don't think my previous post was as clear as it could be on that.

I'm really looking forward to seeing this complete. I hope you are going to spray paint it. The finish will be great!

After a long process of small alterations followed by realising another thing needs to be changed I feel I have got the model a finished stage. Hopefully I will be ordering it tonight and maybe it will even arrive in time for the upcoming Acton Depot open day which I should be attending on the Sunday.

After having to re-do several aspects of the model again I am now happy it is as good as I can get it and so have ordered it from shapeways today. I will keep you informed and maybe even post a photo or two when it arrives.

My PC's fine thank you very much!  Perhaps it is a security setting? Only two of the links don't open first time anyway.... |
