Wagon building SC 630


London cambrian

1,786 views

Today hasnt seen a huge amount of activity so i'd thought i'd do an introduction to part of my current project.

When my dad first started with the wagon building a few years back, his first wagon was a brake van seen previously. then came four wagons then the outside framed box van. My first were the rail wagons and i am currently working on a follow up, two open ballast wagons and a much smaller box van. The van presents more challenge than the wagons so that has been the focus of recent work. These are all Ex metropolitan railway stock, in London transport livery ( post 1933 and possibly even only post 1948)

 

First a history lesson. Very little details of the wagon later known as SC(stores car) 630 are left. it was thought to have been rebuilt from an early ballast wagon built somewhere between 1866 and 1882 by the Metropolitan railway. But the origin of these short wheelbase 2 plank open wagons is unclear, so the Met probably bought them second hand. At any rate, one was converted at an unknown date to a short box van. Despite the vast majority of Met goods van not be passed to London transport in 1933, this one did and ran in various stres train including the Lillie Bridge Ealing common train i beleive, being numbered SC630. Interestingly, one of my other wagons is the next in sequence, SC631 Anyway, details are sketchy, though one thing that is not is the bodywork. All of our drawings are taken from James Snowdon's book Metropolitan railway rolling stock, whom we are greatly indebted to!

At the start of the week i started with a pile of small section wood supplied from a dolls house supplier. Any small section wood will do, preferably soft woods but this time round all i could get was obeche, which is actually very nice and easy to work with.

 

after matching wood sizes to a scale drawing, the corner and door posts were let in or rebated using a combination of a sharp stanley knife and a carefully set milling machine. This allowed planks to sit at a required depth and strong joints to be made.

The frame was glued together with ordinary exterior wood glue. Unlike previous construction, they were dowelled together for alignment and then glued, being left over night to dry.

16mm wide planks were then cut from 1.5mm birch ply, being careful to ensure the grain ran the correct way. These could then be glued in place, each one was given a chamfered top edge that act as a rain run off on the fullsize to stop water rotting the edge of the planks.

Diagonal body frame bracing was then fitted. these milled down to the correct width (nothing appropriate being available) and were cut using a razor saw to shape

Door post were then cut to length and the other pieces in the door frame were also cut. again these were dowelled together. Being a lazy person i couldnt be bothered to rebate the door frame so glued bits of ply running against the planks to simulate a rebate.

Finally planks were cut for the doors and glued, and that is how things stand currently.

So next job is to start adding various bits of strapping and platework, make the hinges and fit the doors, before making the ends, assembling the body and making a rood, sometime by next week.

 

So until i find something else to write about.

Hope you find it interesting. Its really not that big a leap from model railways to this. I did it.

 

Cheers

Looks great!

Fantastic detail, fantastic prototype. (I am a fan of the MET too) I look forwards to seeing more. I just wish I had a larger modelling space makes my 00 Gauge stock seem insignificant compared to this!

I am enjoying this build of yours. It must be very satisfying making something so large.

 

I have often looked a works drawings of old wooden vans, as a carpenter I am always interested in the joints and methods of constuction. Modelling in 7mm you often forget how big some of the bits of timber were.

Do you make all your own iron work? Or can you buy wheels and W irons?

Hi all and thanks

Matloughe, if your 00 stock is Met, maybe get in contact with the london transport museum depot at acton. they're on the lookout for as many met models and layouts for next years march open day, especially what withit being Met 150 next year.

 

Building this stuff can be very satisfying,but at times infuriating. Theres alot of cleaning and preparation before each part is made, and when you come out of the workshop after 2 hours of an evening and realise all you've made inthat time is 4 little brackets, it can drive you up the wall!

Wood work however is the best bit, it tends to show large results quickly. especially in a wekk or so i can have a complete van body almost done. Its also interesting to see how the real ones were done and you realise many wagons didnt have much in the way of carpentry in some areas because it weakened the structure. some mortice or tenon joints but mostly they are held together with long iron tie rods.

 

Iron work generally we have laser cut though the two main suppliers in our hobby, Doug Hewson and Dave Noble do supply iron work, or kits of iron work, especially like w irons or v hangars, and complete sets of brake gear. fortunately most wagon have a fairly standard underframe, except the Met, which had to be different!

 

wheels however are a different story. Doug hewson supplies rough castings for wagon wheels but you have to machine and tidy them up yourself.

Slaters are the other supplier of 5 inch wheels but for a while they only supplied finescale wheels which are not much good i hate to say. A wheel flange and its tolerance are not something you can scale down so they wont run properly through points we have to use. However they now do what they call coarse scale wheels to GL5 profiles which run really well.

for this I'll probably hewson castings because otherwise this van will be so light it will just fall of the track over any irregularities

 

cheers
