Scottish Modeller - The Workbench thread!

Phil you got the colour just as I saw in the video. Super! Lots of neat detail. Good stuff!

Hi all,

Lack of progress on the coaches today - caused by paint problems as masking tape started lifting to topcoat.

Not sure why, all done with my usual equipment, methods and paints/thinners.

Can only put it down to weather and humidity/temperature when sprayed.

Started working on the internals for all the coaches - all painted and now drying in the dryer.

A fair bit of searching to get confirmation that the 2 AC coaches are 925 and 927 but eventually found a video the showed the numbers clearly..

Interior details of the AC coach are beginning to appear as well!

I started with 3 hours spent making 12 curtains, 2 hours designing the internal structure, AC pods and glazing. Then a while deciding how to get the curtains to stay in the right position once inside the coach.

Tested the running ability of the coach chassis and happy that they run freely, level and sit square on the track.

More after the next attempt at the paint jobs!

Thanks

Hi all,

Paint issue resolved.....

Not all acrylic thinners are the same it seems....

So - a fresh batch of acrylic paint mixed with the same makers acrylic thinners resolved the situation.

New coats of paint applied, low tack masking tape this time and remember to use the same for the guiding mask for the decals when I get back to that stage.

More or less sorted the interior of the AC coach - or so I thought.

I now have photos of 923, 925 and 927! Thanks for the help via modellers/DHR fans in India and DHRS David.

Whilst I was studying photos of the coaches (to make sure that I put the decals in the right places) I was struck by something else and now have queries about which coach the kit represents.

The window sizes/positions appear different and also the window and vents for the AC compartment to be different as well.

Then crunch - photos of 925 show that the sc pod on the roof is at the opposite end of the coach to that on 927!

Decide that 927 is the nearest as made - More photos required really.

Now, time to have a rethink and work out how to make the model more like the real thing.

Which is a real shame when I've just repainted it!

Thanks

Hi all,

Back to my AC Coaches dilemma!

Grasping the nettle and showing the elephant in the room....

The PMW AC Coach body as supplied is not correct for any of the actual coaches.

From the various photos and videos I now have there are some major issues.

1) Door windows as modelled are wrong shape

2) Windows as modelled are single pane openings when the real thing has double pane openings

3) Window as modelled to the AC Compartment is wrong size/position

4) Vent as modelled to the AC compartment is wrong shape and/or style

There are some variations between the various coaches, but I've not found any of them have the features as modelled.

What to do?

Not made my mind up. busy thinking through the options.

More photos would be useful though!

Thanks

Just enjoy the models you have Phil. I am quite sure most of us would not know the difference. I was like that once in a different manner. I could not have 009 and Ho run together. I use to bother me to no end. Now I don't care as long as I enjoy the moment and my models.

Hi Robin,

No worries - I'm always up for a challenge!

I'm just drawing up the changes I think are needed and will send it on to PMW and see what happens.

Changing the shape of the door windows is relatively simple - cut and shape then add external frame that holds the glazing on the real thing.

Similar solution to the AC compartment window and vent - but they seem to be different on each of the real coaches.

Adding a horizontal window bar to each of the side windows will be a challenge as the existing verticle window bars are the most vulnerable bits of the 3D print.

Back to Google search for photos and to YouTube for videos.

Screen capture the right coaches off the videos and then match size to the model.

Thanks

ps - I always enjoy my modelling - even when things are not quite right.

Hi all,

To illustrate what I am on about with the DHR AC Coaches

Model of AC Coach as supplied as a 3D Print

I know I don't have the same side for both the coaches - I hve what I could find or has been supplied to me.

Thanks

Hi all,

Made a start of resolving the differences between the AC coach model as supplied and the real things.

First though - difference between the real AC coaches.

There are several differences between 925 and 927 - some more obvious than others.

1) Door windows as modelled are wrong shape

2) Windows as modelled are single pane openings when the real thing has double pane openings

3) Window as modelled to the AC Compartment is wrong size/position

4) Vent as modelled to the AC compartment is wrong shape and/or style

5) Roof AC pod is at different end on each coach.

925 has the AC pod at the door end of the coach

927 has it at the AC compartment end of the coach

See photos above for comparison

For 5) - we will have to live with it as it's a one piece body print.

See photo

For 1), 2), 3) and 4) there are solutions and I'll cover them in the following posts

[Scottish Modeller]

Hi all,

Following one as per previous entry with the following

1) Door windows as modelled are wrong shape

2) Windows as modelled are single pane openings when the real thing has double pane openings

3) Window as modelled to the AC Compartment is wrong size/position

4) Vent as modelled to the AC compartment is wrong shape and/or style

So- First up for modifications?

I'll start with the modification that has the biggest visual impact - in my opinion at least.

2) Carriage side windows are double pane openings - not single pane as on the model.

How to resolve this is actually quite simple - or as simple as making 10 cuts in a 3D printed material can be!

Follow the photos to see how I did this

Photo 1a - Mark existing vertical window bars 3mm down from the top horizontal bar

Photo 2a - Cut out 1.5mm from below the line you have marked

Photo 3a - Cut and Insert 1.8mm by 1.8mm square section 85mm long

Photo 4a - Repeat for the other side of the coach

And that's it - one of the major corrections done

In the next post I'll look at the other major visible difference - the carriage door window.

Thanks

Hi all,

As per previous - moving on to the next thing to correct

1) Door windows as modelled are wrong shape

Still working on the best way to do this as each coach has differences

From looking at the photos of the coaches the nearest coach to the model is 927.

This has oblong windows with rounded corners asnd not the eclipital ones that the model as supplied has.

But, how to do it? Is there an easy way or not?

There isn't sufficient space in the moulding to simply cut a new shape to the window.

So, cut out a larger area and insert a filler piece, then cut the right shape of window into it.

Sounds easy! Well it's not and part of that is due to the brittle nature of the 3D printed resin.

I'll update this with photos once I remember to take them. Done!

Thanks
Phil H

So - having filled in the door window area - what nest?

I'll leave the cutting of the new shape door windows for now as cutting the holes may make the body vulnerable to damage when handled.

3) Windows as modelled to the AC Compartment is wrong size/position

4) Vent as modelled to the AC compartment is wrong shape and/or style

It's that time again!

Check photos before you start cutting and shaping.

More after I've done that and worked out the correct sizes/positions for modelling 927.

Photos to follow once I take them.

Hi all,

Big intake of breath and some deep thoughts about the PMW AC Coach.

Also an exchange of emails with David Churchill on the subject (thanks David - I think).

The bad news?

The PMW coach as supplied is incorrect and not just in the areas I've already gone through on here.

OK - those are errors that can be corrected relatively easily, but....

There are some problems that will either take too much correcting or are not correctable - depending on your level of commitment and skills - makng the model into something that is as correct as possible.

Both sides of the coach have been modelled wrongly

1) The door and window shape as commented previously, plus the door is not inset into the coach side as deeply as it should be

2) The number of windows on the coach side - 6 instead of 5

3) Doors have been modelled at the same end of the coach - should be at opposite ends

Hopefully this makes it more clear to all?

I'll be going back to the guys at PMW and see waht they want to do - I don't know if they will redo the drawings and make a better job of the model, but, if they know, then that is up to them.

What will I do with mine?

Not sure yet if I just have a chop up job to try and correct it or wait to see what the guys decide to do.

If I carve one up to correct things it will result in an intrinsically weak bodied coach model.

Other thoughts - anyone with any ideas - feel free to jump in!

Hi all,

Another day - another box of stuff!

This time is full of 3D printed stuff from Westhill Works.

DHR Class A plus selection of Leeds Forge wagons.

These are all for the heritage period build I have in progress.

So, for the Class A loco I need to find the chassis.

Minitrains 1001 Fiddletown & Copperopolis Locomotive

But, it seems no one has any in stock.

I'd take a complete model but cannot find one to buy.

Unless someone on here knows better?

Or has one they would be willing to sell on.

Just let me know!

Thanks
Phil H

Phil, you have put a lot of work into a coach that has quite a few printed defects. Trying to correct it might create other issues. If it were me, I would finish it and mark  DHR "AC Experimental" That way it can still be enjoyed in a rake.
Minitrains Germany still have painted and printed models of the Fiddletown & Copperoplis locomotives. If your looking for just a chassis, that I think will be difficult. On the other hand I could be wrong.
Robin.

I wonder if the issues with the coach are differences between 'official' drawings and what the workshop (Tindaria or elsewhere) actually built...
