Hi all,

 

OK - So the coach build is going OK and I'll be updating it tomorrow at some point - health permitting.

 

Time to set out what else is will be going on.

 

First a diesel - NDM6

 

Worsley Works Etched body

 

Chassis to use - Unsure as the one that has been supplied is a 6 wheeler and the NDM6 is a 4 wheeler!

 

Will have to consult and work that bit out!

 

Anyway - I've seen the great article about doing a state of the art chassis for this but it's not in the remit or budget for this build.

 

Looks very good though and, if I was building for me, that would be my chosen route.

 

But I'm not - so I may have to accept the use of the chassis supplied.

 

Anyway - first things first....

 

Research....

 

Got loads of photos of several different DHR NDM6's - including plenty of detail shots.

 

Read the article about building an NDM6 which is useful even though I'm not following that route for the chassis as it gives lots of ideas about adding the extra detail and making the supplied detail even better.

 

I'll start with some photos of the etched bits - probably over the Easter weekend.

 

Thanks

Hi  all,

 

Progress has slowed - to a halt!

 

I managed to break my Antex soldering iron whilst doing anothr job.

 

I can't really moan about it - nearly 20 years of service, 5 replacement bits and 1 replacement element in that time.

 

This time I dropped it and, as I couldn't see where it had fallen, managed to stand on it.

 

In the meantime I've started bending the brass on this one.

 

Photos in a while - need to clear the decks before a photo session!

 

Thanks

At least you didn't do what I did once - knocked the soldering iron off the workbench and with amazing reflex action, caught it - but only briefly, I caught it by the hot end. Ouch.

 

Good luck with the build.

Hi Colin,

 

I can go worse than that

Good luck with the build.

 

I have 2 parallel burn scars on one of my arms - gained by rolling over under a layout whilst wiring it.

 

The irony is that I rolled onto a soldering iron that I had put down - and I did the same thing twice!

 

Thanks

Hi all,

 

Whilst researching for the building of the Darjeeling stock I came across this wonderfully evocative bit of film....

 

https://archive.org/details/upenn-f16-0416_1930_Darjeeling

 

OK - so it's from the 1930's and so not in period for the models I'm doing.

 

But - as a piece of historical film - priceless.

 

Thanks

Hi all,

 

Progress!

 

With the arrival of a new soldering iron - I can resume!

 

So - Whilst I had other soldering irons I considered them to be either too big (physically) or to powerful (wattage).

 

So I waited....

 

Whilst waiting I did all the prep work - ready to start soldering.

That left me waiting to get moving onto another stage.

 

Thanks

Hi all,

 

As per previous posting

 

Get some soldering done!

 

First things first - time to tin up all the places where the soldered joints would be.

Although not all parts are shown in the photos I did tin everything!

 

Thanks

 

Next - Now we can do the soldering!

Hi all,

 

A couple of messages received asking  for more info....

 

I use the bit of wood, hardwood in this case, to work on as it protects the work surface and does not absorb as much heat as a tile of bit of glass.

 

It also allows me to pin through holes in the metal to make it easier to tin or solder.

 

I use the softwood, balsa in this case, because it accepts pins easier when holding pieces to be soldered.

 

With a bit of careful pinning it can also act as a sliding support so that you can work easier when you make a hollow piece.

 

OK - so, you end up with a bit of scorched wood marking on the metal - but it comes off easily.

 

Thanks

 

Next - Soldering the body parts together.

Hi all,

 

As per prev posting...

 

The chassis

 

As I commented at the start - I was supplied with a Bachmann Plymouth 3 axle diesel to use for the model.

 

So - it's wrong as it's 3 axles and the real thing only has 2 axles!

 

Option 1 - Continue with the chassis supplied and make everthing under the running plate fit where it will

post-6887-0-28015300-1459522826_thumb.jpg

 

Option 2 - Change the chassis and put everything under the running plate where it should be.

 

Use a Kato chassis - I happen to have one. This would need a different running plate or frame to enable it to fit.

post-6887-0-06053200-1459522864_thumb.jpg

 

Now just need to get confirmation from the person I'm building it for on his choice of chassis.

 

So - comparison of the different things side by side

Now just have to wait!

 

Thanks

Hi all,

 

As a result of documenting the couple of DHR builds I have ongoing and shown on here...

 

I have gained another DHR commission!

 

More on this once the parcel get s to me.

 

In answer to a couple of questiuons that I have received - I've responded direct, but I thought my responses might be relevant to others with an interest.

 

1 - I am by no means an expert on DHR!

 

2 - I take on builds that I see as a challenge - whether that be the kits themselves or obtaining the info needed to do the build - I don't mind.

 

3 - I look at each kit as an engineering challenge - How close can I get to the end result that I think) the kit designer had in mind?

 

4 - My first etched kit build was a Mallard GWR Autocoach - way back when they were the highest standard of kit available!

 

5 - If you don't ask - you don't find out!

 

So - I'll just carry on the way I am and with how I do things and hope to satisfy the people that get me to build things!

 

Thanks

 

Now - Back to the modelling!

 

I mean you - not me!

Hi all,

 

Update on the NDM6 build...

 

Decision is - Use the Kato chassis so that the rest of the under footplate fittings go on at the correct place.

 

New footplate marked out already - just got to get it cut.

 

Hopefully will have progress later tonight.

 

Thanks

Hi all,

 

Not - As per previous posting....

 

Changed as have to have this bit done before soldering details onto the body

 

Setting out a chassis.

 

OK - as I said, the chassis/power unit question is resolved and the Kato chassis gets the task.

 

To make this an easier and removable power unit is the task tonight.

 

In a previous post I showed the rough mark out for what I thought I would need to do.

 

Now - I have done it and, for anyone thinking about doing the same, (or using the same Kato chassis for other things) a drawing with measurements for you.

If anyone wants a larger image - let me know.

 

Thanks

 

Next cutting out the sub chassis

Hi Eric,

 

Thanks for this photo - probably the best side on photo that I've come across.

 

It's proven very useful at giving me the correct positions for things like the steps.

 

If you have any more photos - please share with us.

 

Thanks

Hi all,

 

As per previous posting....

 

Making a sub chassis to mount the power unit.

 

OK - so I had already marked out (and changed) a template for this and then marked up the metal (and changed it again).

 

This is a situation where measure more than once saved a bit of time - and brass sheet!

Now I'm happy with it!

 

Thanks

Hi all,

 

A bit of thinking ahead .....

 

I'm going to need to put decals on this and the coach I'm building.

 

I've searched in a variety of ways but cannot find any for 000.

 

Surely there are some available?

 

With the popularity of DHR I would be surprised if this isn't the case.

 

Anyone got any info re this?

 

Thanks

Oh, wish I could help but I was just going to print my own.... I'm doing a HOn30/HOe version!

Hi Sarah

 

If I get some decals done - they will be rescalable.

 

That should make it easier for anyone else doing the DHR NDM6 in future.

 

Not sure if I should look at including other lines that have NDM6 power - will have to think about that later.

 

This side is fairly easy to do

 

post-6887-0-54636200-1460038182_thumb.jpg

 

The other side is more of a problem.

 

post-6887-0-10468600-1460038194_thumb.jpg

 

The English script is easy - but I'm now trying to find details of the relevant font/typeface/characture set for the Indian Railways in what i think is Hindi Script.

 

Thanks

 

Please note - Photos used were supplied to me unacredited - Apologies if they are yours - Let me know and I can fix it.

Hi all,

 

As part of what I said about getting NDM6 decals done - I started searching.

 

So - which railways have NDM^>

 

Officially - this is the Indian Railways listing.

 

Displaying all 6 locos belonging to NDM-6 Class Locos .

 

Loco No     Loco Class      Shed Code      Comments
600            NDM-6             NRL                 Air brake only 
601            NDM-6             TDH                 Air brake only
602            NDM-6             TDH                 Air brake only

603            NDM-6             NRL                 Air brake only
604            NDM-6             TDH                 Air brake only
605            NDM-6             TDH                 Air brake only

 

OK - I've already had a search for the Neral locos - I thought some aspects of modelling the DHR locos was difficult - I'm glad I'm not doing a Neral one!

 

So - in terms of decals - forget the Neral locos - they seem to have blue/white, green/yellow and orange ones.

 

Back to searching for the typeface/characture set/font....

Hi all,

 

One of the contacts I have made has sent me a photo - of the inside of an NDM6 cab!

 

post-6887-0-60289900-1460042229.jpg

 

At least - I think it's an NDM6 cab!

 

I'm confused as the windows are different to what the other photos show.

 

So - there will be something like this to hide where the motor unit is protuding into the cab.

 

Thanks
