7mm The Colonel's Birmingham Bodges. EMU's & now Mk2 coaches.

How about two rows of pins to act as spacers then place the square bits down flat then solder the bars to the square bits. the pins should keep the bars square

 

[iploffy]

Somewhat similar to a possible solution I think may work yours being much simpler and therefore more acceptable the only thing that worries me is how thick are the shanks of drawing pins as these would be the spacers between the oil pipes. The brass covers would have to be put under them to be able to solder them together then the pipes would have to be bend to 90 degrees then the further spacer put on(copperclad)as it runs behind the whole cooler group

 

[marsa69]

Use thin panel pins and try to bend the lot before you solder them to the brass covers. I think

 

[iploffy]

Can't be done like that after the wire has been soldered on to the brass the Copperclad will have to be threaded on to the ends of the wires then the wires taken round the back through another 90 degree bend and them soldered together. The reason for the copper clad is to give the larger pipe to the transformer and the bleed pipe something fairly substantial to join to.

Hi Ian,

very interesting project, looking good and best of luck with the rest of the work.

cheers

Got a bit further today built a jig to construct the Fins for the oil cooler, not entirely satisfactory but it works so I constructed 2 and fitted them to the bottom of the motor coach. The coach itself is in a proving coat of red primer and has to be rubbed down again

 

[iploffy]

Right the state of play as of 10 mins ago, re think as to the window problem. I have decided to try a radical different way to make the sides as I am not entirely happy with the thickness of the walls of the coaches, borrowing an idea from the 4mm boys and having the sides etched including the 1/2 etching of the window frames (to be fitted with a full depth etch to give the required thickness to the frames) is this going to work, does anyone know anyone who will do the drawings for a Fee and where can I get them etched.

Help please

Ian

Good stuff

Theres a few things to bear in mind when modelling the 310s or 312/2s. One that doesnt affect the model is that the 312/2s were not 100mph, they were resricted to match the 310s

The unrefurbed 310s were not gangwayed throughout. There was no gangwat between the MBS and the TS.

The bogies on the 310s and 312s were all different.

The layout of a 310 MBS and a 312 are different.

310s has axle mounted disk brakes (except the MBS) 312s has wheel mounted disks thoughout.

The vents on the MBS seem to be in random places.

The three headcode dots are always at the DTC end.

Ps have you asked southern pride if they would consider scaling up their 4mm etches?

First time I've stumbled on this thread... what an awesome project! You're doing a fantastic job!

Unusual subject matter and created from budget raw materials. Nice one! Love the attention to detail in your research. I'm looking forward to seeing it with the window/door apertures cut out.

I'll be watching progress here with keen interest; a GE 312 is on my "one-day" list for a Lv St-Cambridge route OHL layout.

Jim not according to the drivers we have at Wolves and the literature they have

The unrefurbed 310s were not gangwayed throughout. There was no gangwat between the MBS and the TS.

Jim check out the extreme end of the panto there is a gangway. There was a partition wall at the end of the Guards van that stopped the passengers walking through the Parcels area. Later they shortened the seat and added a door

The new door looking through the coach

The bogies on the 310s and 312s were all different.
Agreed lateral dampers added to the 312's for a higher speed.


The layout of a 310 MBS and a 312 are different.
Not enough information at this time as I am trying to get the outside correct

310s has axle mounted disk brakes (except the MBS) 312s has wheel mounted disks thoughout.
Agreed.

The vents on the MBS seem to be in random places.
Not checked this out yet but the roof vents are dotted around but I don't know why

The three headcode dots are always at the DTC end.
Yes the First class end

[Jim S-W]

Are you sure they have literature for the original 4 312/2s?

Unrefurbished 310s were definately not gangwayed between the MBS and the TS. The end mouldings were the same (as in your pic) but no gangways.

The 312 bogies (the traliers) were closer to b5s than the b4s on the 310.

I meant the layout of the doors on the MBS. The 310s having an extra door for the guard. But the vents i also meant the bodyside vents, sorry for not being clear.

Also of interest there was an odd driving car rebuilt from a TS after the stafford crash and at least one unrefurbished 310 got NSE livery. I havent been able to find any evidence of a refurbished 310 recieving blue and grey.

[wyrleybart]

From memory there were several differences among the 310s. IIRC sets 091 and 094 were oddballs at least. AsJim said the 310s were only orginally gangwayed between each pair of vehicles, but did this change with the 310/1s for Midline ? I know the 312s wer ehangwayed right through, and as Jim said, the 312s had just a pair of doors in the brakevan, whereas the 310s had a seperate guards door.

Interesting project

 

[Simon Dunkley]

310s were built semi-gangwayed, and at some point in the early 80s, we're gangwayed throughout, but only for the guard. This happened whilst they were all still at Bletchley, serving the southern end of the wcml.

Jim didn't say that the 312/2s weren't capable of 100mph, merely that they were restricted to 75mph to ensure compatibility with the 310s.

The four LMR 312/2 had a lower gear ratio to match the LMR 310 (63:17) and thus 75mph, the ER 312/7 were set at 61:19 which gave 90mph....according to my book of words? Mind I always thought they were ton'rs myself, but it appears only the 309 'Clactons' were capable of 100mph in that era.I think the Bed-Pan sets were the next to get 100mph capability when introduced in 81.

Eventually the LMR 312/2 were transferred to the ER and became 727-730 and I presume took the same ratio as the rest of the /7 series to maintain capability, I am not sure when this happened as my spotters books only go up to 1982 and it was after that.

 

[Simon Dunkley]

Bugger.
Serves me right for not checking against published sources!

 

[iploffy]

Listen guys, I'm not particularly worried about how fast a unit can or can't do particularly as they've been scrapped and as Jim says in his initial paragraph

One that doesnt affect the model is that the 312/2s were not 100mph

I'm trying to model the train not the performance. And no dis-respect was given on my part as far as I can see

 

[iploffy]

Your only jealous, So what if I have the bullet train in my back garden it's my BLUE trainset

Would like to see some progress pics Ian

Rob

 

[iploffy]

No progress at the moment to talk about, Unfortunately rushed off me little tootsies, so is the Sarge. With the rethink on the sides there maybe a flourish of activity if we can get the sides etched, until then it's the underframes and ends only

 

[iploffy]

Well I ordered the Resin today from Sylmasta Ltd (thanks Simon) to have a go at the ends firstly a Master which I will be taking care of whilst I ain't got the car on Sat
