Diemas Ain't What Dey Used To Be

(With apologies to S J Perelman)

Back in November I posted an item in the Trade section about a kit for a Diema loco in 7mm scale, made by Graham Baker, which I bought with an eye to bashing it into a Gn15 Diema might-have-been.

Image

I finally got it onto the workbench to make a start but, after a lot of measuring and comparison with prototype pics and other models, decided that it was a bash too far. The footplate and engine compartment are very narrow for Gn15, so I would have to shorten and widen the footplate, as well as shorten the engine compartment casting. I have doubts about an inside-framed loco in that scale anyway, so I decided to build a Diema-like from that magic material, scratch.

I took the kit up to Burton a couple of weeks ago, hoping to sell it on the 7mmNGA second-hand stall but found no takers, so I'm assembling it as intended by the maker (there's a first), with a view to trying to sell it in that state. There were no instructions with the parts, so it's been an interesting build, now ready for painting.

Image

Meanwhile the plasticard and Plastic weld have been deployed and a basic footplate and engine compartment achieved. The comparison between the 2 engine compartments shows the disparity in width:

Image

I am basing the Gn15 version on the Diema DL8, and found a web site with photos of one of this model dis-assembled into a kit of parts for restoration http://www.zonetopic.com/17455022792-diema-dl8

There is also a drawing of the DL8 at http://www.buntbahn.de/modellbau/printv ... 67&start=0 There is some vertical distortion, but I down-loaded the plan and stretched it to make the wheels circular, so I'm using that to get some basic dimensions. They match the dimensions of Wot-the-Deutz quite well, so something must be right.

Progress so far:

Image

I'm now working on the axle-boxes, cutting out lots of tiny pieces of plasticard and losing half of them in the carpet. Onwards and upwards :roll:

(With apologies to Bilco): Kit or scratch build ... that's a dilemma.

Looks great - seems like scratch was a good choice.

WOW Bill, now this I like a Diema in right size :D

I did a scratch built DL6 some time back, Hn15 or Gn15
Not the best result but I'm satisfied with it

Good luck on your's looking forward to see it come to live

Hi Hans - Thanks for the pictures of your Diema. Nicely done, especially those axleboxes. They are quite intricate little pieces, but they make the Diema identity plain. I've just finished the basic 'boxes and am now resting my eyes :shock:

Image

Not a great picture, but I hope the appearance is about right. They just need those characteristic adjusting rods to complete.

That's some great detailed modelling Bill. I'm looking forward to seeing this loco progress.

Well, some progress, but a bit slow because of other things filling the time!

I've fixed the axleboxes to the frames, and added a bit more detail to the engine compartment, as well as lashing together some bits and pieces to make the gearbox. Still lots to do before the trauma that accompanies my attempts to paint the beast. :oops:

The bulk of the gearbox and the lid for the sandbox are leftovers from the UE bodies I butchered recently.I have some couplers ready to fix into position - where the pencil marks are - and I have some brass etched grill material to make the various doors. All I need is time :roll:

Looking real good, keep up the good job
What have become of your 7 mm scale Diema?

That's coming together nicely!

Talking about 7mm Diema's: Can't wait till KB scale's tiny DL6 will be released :)

Many thanks for the kind comments chaps - progress is slow, and is about to get even slower, as we're off on our hols on Friday!

The 7mm Diema kit is painted, awaiting weathering. I shall weather both together in due course, but it's very disorientating, making models in 2 scales simultaneously :shock:

Image

A cruel close-up of the 7mm Diema. The upper works aren't stuck on - that will come later, after the weathering.

I'm working on the grills on the Diema-like, trying to make them out of plastic sections and etched-brass grills. I may be some time :roll:

The 7mm one does look very nice, I seem to recall looking at the kit at Burton and being tempted, then reminding myself that I don't model in O-16.5 :roll:

Well, I didn't get away on holiday as I had hoped - a case of life being what happens while you are making other plans! Anyway, life has calmed down now and I can think about the Diema-like.




Image

Progress of a kind - I've got the grills cut and resting in place, and they don't look too bad. The letter R is so I get the right one in the right place :roll:



Image

A front view. The big brown rods will be cut down and be part of the clips holding the grills in place. The couplers are from Steve, but they looked a bit weedy when I first stuck them on, so I've beefed them up a bit.

Still plenty to do!

After I posted the pictures 2 days ago, showing the etched brass grills on the side of the bonnet, I began to feel that there was something not quite right. In the end I decided that it would be better to open up behind the grills rather than try to paint black in the background.


Image


With a bit of drilling around the edges and some hacking with the trusty modelling knife I opened up inside the framework of the doors, leaving just a little ledge for the brass grill to rest on (the black line). I also thinned the edges of what is quite substantial plasticard (for strength).


This bit of butchery didn't take as long as I thought, but when it was finished I began to think that something was missing - again. In the prototype photos it's possible to see the engine behind the grills, so I trawled through the bitsa-box and found another box from the UE Inspection Car, as used to make the gearbox, and used that as the basis. After sticking some random bits and bobs on the box I decided that it sat too low, hence the bodged-up base.

Then I thought it would be nice to connect the gearbox and engine, so stuck in a bit of old cotton reel, and removed the solid wall that the gearbox had butted against.


Image


Any resemblance between this and any real-life engine is purely unintentional. And, of course, when the engine compartment cover is in place you can't see anything of the engine :roll: At least from the driver's end you'll be able to make out something lumpy and oily in the depths of the compartment.

Bill,

nice modelling, been interesting watching this one develop .

:shock: Why didn't I think of that...I have not an engin under my hood
just the parts that shows. Very nice jobb, it's looking real good.
Think I'll have to look closer to your pic's so I can learn a few new tricks
Thank you Bill

Many thanks for the kind comments, chaps. Progress continues to be made - very slowly.

Image

The grills are now fixed in place, and a back sheet is on the way - I just need to make the brake handle in the unusual Diema form.


Image


A view into the engine compartment - lumps, oily, Diemas for the use of :roll:

A cruelly-enlarged shot of the grills - but at least you can see the engine behind :D


Image


You can also see the catches to keep the grills closed - more fiddly little bits of plasticard :roll:

Fresh out of the paintshop today, with little of the normal trauma - apart, that is, from dropping the still-wet engine compartment onto the garage floor - don't ask :x


Image


A side view. The colour scheme is influenced by the photos of the real thing being rebuilt http://www.zonetopic.com/17455022792-diema-dl8.


Image

Front view - if you look carefully you can see the engine behind the grill!

From the rear showing the engine in the depths, and daylight visible through the grill.

The bits are just resting together at the moment, pending a little work on weathering and touch-ups. I can't bring myself to do much weathering - well, all right, just a little :roll:

That is interesting I have the same disease :wink:

Hey Bilco

Can you tell me which grills you used for this loco? I need one to replace a white metal moulding and I'm looking at A1 Models atm. I need one in 7mm scale but hopefully any supplier will make different size options.

Looking good btw, any more progress?

Cheers!

Hi Christian,

Yes, the grill material is from A1 Models - ref AS 04. It comes in an oblong piece about 18 cm x 6.5 cm. I got it at the 7mm AGM at Burton in May. They have some grill material with circular holes as well, which might be useful one day!

I'm fiddling with little details at the moment, on the Diema-like and the 7mm Diema, trying to get psyched up to do some weathering. Maybe tomorrow :roll:

Well, the 7mm Diema kit build is finished, having given it a quick spray of DullCote today. It's had some light weathering overall, with some spots given a bit more to hide the dodgy areas :oops:


Image

Front view - doesn't look too bad from this angle.

Image

From the side and, allowing for parallax, reasonable. Some heavier rust at the bottom of the cabin where there was some poor fitting. The seam visible is cast into the side, and not really worrying until the weathering showed it up!

The pics are taken with my old digital camera, as the new(er) one stopped working yesterday. I have a nice shiny new one on order from Amazon :shock:

That turned out nice Bilco. You did well.

Very Gnice work Bill. The details look superb. The engine through the mesh gives the green loco real depth. It looks even better on the layout, at work with a skip.
