Class C ECMCHAS For Silver Fox Kit.

[murrayec]

I kept going on the C today;-

I turned up a few brass hoops on the lathe for the side window frames.

Made up a new buffer beam coupler reinforcing detail from .3mm styrene, the front coupler will be a prototype screw one.

Scored out the lift-out panelling on the roof, drilled .5mm holes and made .45 nickel silver lifting hooks which will be metal blackened and installed after the body is painted. One is installed at lower right.

Side window frames on

and front buffer detail glued on with epoxy.

Just a small bit of cleaning up the epoxy in a day or two and then painting can commence...

I was reflecting on the roof details of the model today after seeing IRM's A at the Fair yesterday, and decided that I would wipe the rear roof ventilators off and install the exhaust as the SF body is devoid of an exhaust opening!

After browsing through my reference photos of the Class I found a silver liveried one with these rear roof ventilators, with the exhaust opening in-between them- a much easier job!

Drilled out a 5.7mm hole between the ventilators and cut a hoop from 5.5mm styrene tube to trim and make an up-stand to the exhaust.

While browsing the photos I also decided to add a little more detail- door handles to the louvred doors with .3mm brass wire epoxied on and trim detail around the lower body openings below and in front of these doors, the same lower detail was done on the other side also.

The lower detail might get a rub of a file when the epoxy fully sets as they look a bit over scale, though a few coats of paint will improve their appearance by not contrasting as much as they do now.......

After an informative comment on the exhaust on fb yesterday- the fact that C's had twin exhaust ports! I decided to modify my single port to a twin.

The old styrene hoop was forced out and the hole filled with a 1mm styrene disk.

Then 3mm holes were drilled and broached to take 3mm dia thin wall brass tube.

A little bit of filling needed around the styrene disk......

Shame to lose that nifty fan but c'est la vie

@DiveController The fan is at the other end and it's still in,

I'm now considering a smoke generator for the exhaust! the only thing was the colour of the smoke- 'C's' belched out black stuff and the generators do white/grey?

[DiveController]

Cool, dude! If I ever get round to commissioning something you're the man. Cracking little job this.

[DiveController]

I was looking for a decent picture of the roof of a C class which proved difficult. They may have differed after they were re-engined of course but this was the best I could do with the fan end rightly protected from the elements. I'm not seeing much in the way of exhaust ports at all tbh

I have a Silver fox C class and thought the exhaust holes where in the middle where the small rectangles are.

So i made two holes there and filed the sides flat. I have posted a picture of it below.

I was watching a youtube video from ITG starting their C class and the exhaust smoke was coming from the middle two holes.

Perhaps this was changed when rengined.

 

[DiveController]

Hmm, that would seem to make sense why the ITG have those areas covered. Don't know too much about the innards of the A or C classes at all. What area the various vents & grilles for? 

[NIR]

The top and side grilles would be for the cooler group, the radiator basically, and the vents would be air intakes.

[murrayec]

This is the photo of the roof I worked from, hard to see exactly what's there but exhaust smoke is coming out of one of the ports- why at first I amused one port! A chap on fb posted a picture of two ports and confirms this is correct;-

The exhaust ports were moved when re-engined, I reckon popeye has it correct

[NIR]

Lots of photos of NIR 104 Class

 

 

[DiveController]

Those photos really tell the story for the original and re-engined versions. No question your smoke is black with the Crossley engined one, I think, which says a lot about the heavy weathering on the roof and even sides

So it seems to be that you can do either.

It depends what livery you paint it, early ones would need the exhaust done like yours.

 

 

[DiveController]

Exactly, anything like Eoin's in BnT or earlier. Anything in ST would already have been re-engined.

@popeye Thanks for that drawing, very helpful indeed.

C233 & C234 got Maybach engines (initially) in '65/'66? They kept these until they finally got GM engine in '79/'80, most of the rest of the C class having received theirs by '72.

 Wonder what that looked like?

The painting started last night, first was a light coating of etch primer to the metal parts. I decided to paint the chassis also.

I was going to metal black the roof plate lifting hooks and stick them on later, but recently saw a photo that showed them in the same colour as the body, so I stuck them on and primed them to.

The bogie sides were 70deg soldered to the brass motor out-riggers, thinning the brass with 180deg solder first.

Some of the sides detail going on- brake pull rods and a bit of over frame piping, I'll hold off on the ladders until the body and chassis are out of the paintshop just to get the alignment right!

The front of the bogies is looking a bit crude so I have worked up a drawing to do a front crossframe and revised wheel guards, the guards cast on the bogie frames are way out from the track.....

You're doing it in silver? That will look amazing!

Hi JB

Yes, it's going to be silver

Another master class. So much to admire and learn from here.
