CDR Railcar No. 10

[ge_rik]

PS - Mk 1 of the seats look reasonably ok. A bit more tweaking required but hopefully by the time my new supply of filament turns up, I'll be ready to go into mass production.

The texture of that looks really like it's actually upholstered. Very nice.

It's been a while since I posted an update - but a lot has been happening. As you will have seen, I've been running trains in the garden during the fine weather - and also, I've been tinkering with the 3D printer. It is a bit like a needy child, but I'm beginning to get to grips with it.

So, a lot of time has been spent in making the roof for the passenger trailer car.
Two laminations of basswood which had been rasped, filed and sanded - then filled and sanded a few more times. It's reached the stage where I can apply a couple of coats of primer, which reveal more blemishes which will need filling and sanding.

The rear end has also required a lot of work as all the edges are curved. Again, more basswood and filler and loads of filing, filling and sanding.

The seats are slowly being printed. I've been drawing, downloading and printing other things in between. The seats take about 25 minutes and the backs about 35 minutes to print - but the cost (not including electricity) is minimal - around 15p per seat.

Looking forward to applying some paint!

Looking great Rik, the curves may be hard work but well worth the effort. It's a very nice model and will look lovely when running.

[ge_rik]

Thanks Peter
I must admit, that I have wondered if I could have drawn a 3D model of the roof to print off - but maybe that's a bridge (or a roof) too far at this stage in my learning process. I will be glad to clear the air in the workshop of dust from the sanding, though!

compound curves are always a pain, we would use a lot of blue foam in the RC scale aircraft world as easy to carve and sand but not as "Ding" prof unless glassed afterwards

Hopefully, the railcar won't be getting too far off the ground and so prangs (as I think the good old handle-bar moustache chaps used to call them) are going to be fewer and farther between than in the RC aircraft world.

Rik,
Looking at the picture of the white seats, you seem to have a pincushion/pillowing effect on some of them. Not sure if its just the internal structure showing through or if it's an actual physical effect? However, the way to get rid of it is to increase the number of top layers in the slicer. I used to use 3 or 4 top layers and had a big problem, particularly with low infill %, but a professional 3d printing guy told me that he tends to go up to as much as 10 layers - the more layers the less flexible and less prone to deforming.

Thanks for that tip, Philip. Another setting to investigate.

This is looking great!

Sorry to be a cliched trainspotter, but what livery are you going to go for?

Cheers,

Andrew.

I thought I'd go for the line's passenger stock livery, maroon. I was tempted to keep her in CDR livery of crimson and cream, though.....

I was wondering whether you'd resist that temptation!

Looking forward to seeing it...

I can only agree

[ge_rik]

All the seats are now printed, the passenger trailer is more or less finished and so today received a couple of coats of primer.

Still a fair bit of filling and sanding to go and also a few more fittings needing to be made and attached - but she's beginning to look the part.

...she's beginning to look the part.

She really is!

I was looking at some photos of Irish railcars lately, including the ones that ended up on the IoM - are you sure you couldn't be tempted into "updating" your passenger livery for this new-fangled form of motive power with a nice cream stripe??!

Looking forward to seeing the finished thing snaking its way round your garden...

Very tempting! I might give it a try...

Thanks for the link. There's also a very good picture of No. 10 in her Clogher Valley days on there which I've not seen before.

Further update. It's been a while since I posted on progress, but I have been steadily tinkering away with the railcar. I tend to have around three projects on the go at any one time so I can get on with something else while waiting for paint to dry or for stuff to arrive.

All seats now printed, assembled, painted and installed and she's been through the paint-shop. There's still more to do - mostly tweaking and finer detailing - and (as is always the case with my projects) a bit of remediation. However, she's now looking more presentable.

A bit more work needed on tidying up the bonnet and the cab roof will be screwed into place once I've finished tinkering with the electrics. The loose cable in the cab will eventually provide lighting for the passenger compartment.

The steps need painting and weathering and handrails need adding. I'll also print out some luggage for the roof rack. I'm looking for a basket of chickens or geese which I think will add a agrestic touch! I can't disguise the join in the roof, unfortunately. Maybe, once I've peopled the interior and installed the lighting I'll just fill it, sand it and paint it and hope I won't have to reglue the passengers or sort out lighting problems!

My hard work on the filing, filling and sanding of the tail end seems to have paid off - as long as you don't look too closely! I'll add a swivelling coupling to the rear as initially, I want to tow a luggage van but eventually add a dummy railcar to make it double ended - thereby avoiding having to install turntables at each end of the line!

It's been a challenge putting together a bare bones etched brass kit without instructions and with no additional fitments and fittings, but I am quite pleased with the result. I know there are modellers on the forum who would have produced a far finer model - but this has very much been a learning experience. I'm not sure I will rush to make another brass kit. I am much happier working with plasticard - particularly as I can more readily cover up my mistakes - or maybe avoid making them in the first place.

Brilliant Rik..... I think you have worked wonders from the materials you began with and have had to learn new skills on the way to completion. The final touches you propose will all help to take the eye from any slight imperfections, which probably only you would be aware of..... stop pointing them out!
The overall effect is what we are aiming to achieve and when in the garden doing its day-job it will be something to be proud of.

[LNR]

I agree totally with Peter, considering what you started out with, missing items and instructions etc. you've ended up with a nice working model. Well done.
Grant.
