"Iconic" Sounds like a good name, for a distinctive loco..

Or "Ironic" if the rest of the build goes badly...

It did last night, when I underestimated the power of my daughter's hairdryer which I was using to bend the front of the bonnet. It buckled horribly, so it's off to the model shop for another sheet of plasticard...

Or in front of it, I suppose, given that the radiator's at the back. Modelling the louvred shutters in the closed position should help...
The attached builders photo is I think the second K-S 60HP diesel, b/no. 4418, which was sold to a railway in the Sudan, hence :shock: the open cab. More importantly, it has an engine cover between the radiator and the front plate of the cab. I've never seen a clear enough photo to tell either way with 4415, but it was a prototype, so may not have had the cover. I don't think this pic was taken in Sudan either......... :roll:

Those perforated metal doors would be interesting to model, not.... :shock: The louvred doors on modern diesels are bad enough.


Welcome to the lottery of heat forming polystyrene sheet. It's a very fine line between softening the stuff enough to form it and releasing the internal stresses so that it shrinks and turns into something resembling a potato chip. Acrylic is much easier to heat form as it turns rubbery, but doesn't shrink appreciably, when heated.

If all else fails, I've been known to 'plank' sharp bends and use filler and sandpaper to form a smooth curve in polystyrene.

That's a great photo of the Sudanese Kerr Stuart, thank you! Very good news about the engine cover - I think 4415 mnay have had some mesh, but this will be lots easier! The bell's a tempting addition too...

I'm very pleased to see one in lined works grey as well. It's a long way off, but if the build goes well I've been thinking that I maygo for that as a livery. The idea of my model is that KS also tried out a prototype of the 30HP loco on the WHR/FR, and that, in my parallel universe, the railway could afford to buy it, unlike 4415. If that had happened, I reckon it would have ended up green, like the Ffestiniog's other "tractors", but it's so much more recognisable in grey. Lined photographic grey would tick that box while being a little different too, fit the "trial" thing, and - hopefully - look nice! I didn't know there was a prototype though, unti I saw your photo!

I'm grateful for your "Plan B" re the bonnet too - I imagine I may well end up needing to use it! It's a shame about my first attempt - it went pretty well apart from a couple of wrinkles at one edge, which I just couldn't get rid of...

All the best,

Andrew.

Which were named after White Star liners, according to Wikipedia: https://en.wikipedia.org/wiki/LNWR_Teutonic_Class

Fascinating locos, and a huge challenge to model, I'd imagine??

I bought it as a "project".

-motion seized solid
-valve timing is off
-some small bits missing
-painted with a tar brush.

The model is a real three-cylinder compound.
Will take some time to get her back to running order.

Hello!

It took some doing, but I think I've got the front of the bonnet sorted. I won't really know until I prime it, but I hope it's going to look OK...

On the original, the hatch seems to have given access to the gearbox (replaced by an additional door in the side on the Sudanese version?), but on the model it will allow me to get to the on/off switch and charging socket.

Radiator and engine cover next, I think, but only when I'm back from a holiday...

Cheers,

With all these kits now using laser-cut acrylic:

Is it worth giving the faces a very fine rubbing down before assembly?
I am thinking it will 'key' the surface, for when you come to paint?

Hi Phil,

Yes, that's the plan -I think it's recommended it the kit instructions. I've resisted much rubbing down up until now, because I'm quite enjoying the novelty of a see through loco!

Once I've finished the basic bodyshell (I'm nearly there!) I plan to prime it to see if any further filling is required, then work on all the details before more priming and painting.

I'm not sure yet, but I might pause for a bit when the first phase is complete - there are several projects I put to one side to focus on the loco, which I possibly ought to get back to. Then I could detail the new body as opportunities arises me over the coming months, and put the old RH body back on the chassis in the meantime. Of course, all of my planning is pointless really, whatever happens will do so because it suits the mood that I happen to be in...

Cheers,

Andrew.

Hi all!

Been on holiday (Mallorca, but the wrong side for the lovely trains and trams), so slowly catching up with GRF posts.

I spent a little time yesterday fiddling about with a little gizmo to hold the on/off switch and charging socket in place on the KS diesel.

Here's the finished thing, which I'm quite pleased with - it's not beautiful, but it appears to do the job...

Here it is bolted to the floor through the hole which accommodated the driver's seat on the Hercules, and with the switch and socket in place:

And with the body in place, demonstrating how the switch and socket are accessed through the front hatch...

That's all for now!

Very neat and workmanlike. Well done.
How will you hold the cover in place?

Thanks! It's unusually well designed for me...

The cover has a chunk of 5mm foam board on the back, the same size as the hole, so it kind of plugs in. Seems to work pretty well...

Room under the bonnet for a tiny magnet if required?

Good thinking!

I've got some, somewhere, so will bear that in mind as the build progresses...

Morning all!

Here's the latest progress on the diesel, with some filling, sanding, and priming done, and some more to come. I think I've got away with my "cut and shut" operation to shorten the body...

I rather like the yellow primer livery!

Once it's all tidied up I think I'll put it away for a while and carry on with some other projects, then add the details over the winter and paint in the spring - although there's a good chance I'll change my mind!

Cheers,

Andrew

I can't see any evidence of the cutting and shutting and it looks like a 30HP Kerr Stuart. You've done pretty well I think.


I'm sorry, but I'm a Melburnian and with it painted yellow, it inescapably reminds me of the 'Yellow Peril'......... 8)

Given that I had to turn the chassis round to get the body to fit, there's probably an "Edam/Made backwards" joke in there somewhere, but I don't think I'll go looking for it...
