Thanks Paddy.

I think we should look on 3D prints as being "kits", and like brass or whitemetal or even plastic kits, getting them to look good takes work, priming, painting, decals, varnishing and weathering.

I think the only differences you'll see in the Smoothest Fine Detail Plastic are sharper edges to the details, all of which will get 'softer' with finishing.

The only design tweaks were making the top platforms a smidgen wider. (I'd taken measurements from drawings, but they looked too narrow printed when compared to photos.) I also adjusted the spacing of the bits that engage with the NR-121 chassis, but people may choose others depending on their prototypes.

I rather pretentiously included riveting where the anchor is attached to the tank's welded bracket and three clamps to keep the lid on, but I'm making "layout" models for myself here (that's a Minitrix 9F up front! ).

Some new visitors spotted in the yard:



14T Class A (right) and B (left) tank wagons.

I suspect the B, a tar wagon, is going to be much dirtier before long!

And so it's turned out. Peco tanker ladders modified to fit.



Today I received a set of the N Gauge Society's Chemical TTA decals, so will get on with producing an ICI ferry chemical wagon using my 20T Class B tank and a Parkside Dundas 12' wheelbase chassis.

Hi Mike,

this is one of the wagon conversions I need to do for my period, so - I will be watching with interest!

Thanks

Well that must have taken some guts to weather that lovely tanker.  Fantastic modelling @maridunian.

Kind regards

Hi Phil - towards the end of Paul Bartlett's photos of these, there are some general arrangement drawings. I either need to make the PD chassis longer, or a Peco 15' shorter!

Thanks Paddy. It's always reversible and if that failed I can easily get some more from the shop!

The 14T tar tank is joined in the yard by a 20T chemical ferry tank in ex-works (ie just decalled!) gloss. My 3D printed tank mounted on a shortened Peco 15' wheelbase chassis with a brake man's platform fabricated from scrap and a P and D Marsh brake standard.



Ladders and other detailing still to add, plus a matt finish.

Hi @maridunian - these are looking scarily excellent and as you say too good to throw away.  Can't wait to see that the difference is between these test prints and the finer versions from Shapeways.  In the past, I have not liked 3D printing as it always looked "rough" to me but the technology must be improving swiftly.

Very impressed.

Paddy

Hi @Paddy. Here's a Smoothest Fine Detail Plastic 20T tank straight out of the packet.



Obviously it will now need cleaning, priming and painting - I'll photograph each stage.

By the way, I ordered this on Sunday, 17th Nov. It was printed in Eindhoven, Holland on Monday and delivered here to my village in southwest Wales by UPS this morning. That's standard, not priority, production and postage!

Hi Mike ( @maridunian )

What excellent service and it seems 3D printing is getting finer all the time.  Love the blue gloss tank above - very smart.  Breaks my heart to think you are going to weather it.

 :(

Kind regards

There's a whole thread in this area all about cleaning 3D prints, but I said I'd record what's involved in preparing and finishing one of my models, so...



I soaked my models in white spirit for a day. Note the seasonal pot - not from one of this year's puddings, honest. Some surfaces show a fine honeycomb of support wax not removed by Shapeways. This has softened to a goo that can scraped off with cocktail sticks, coffee stirrers etc - anything that's tough enough to shift it without scratching the underlying plastic.

A good scrub in warm (not too hot - SFDP softens at 80C) water with a generous squirt of washing up liquid, then a thorough rinse in clean warm water.

A light rub down with fine wet-or-dry paper/emery boards keys the surface for priming.

Thanks Paddy - a light rub down to deal with that faint central line, another dusting of primer (probably with fine details masked) then gloss black to follow. Fox SHELL/BP decals already sourced.

The pristine 20T Class B awaits the sign-writer, who's still finishing off the ICI Ferry Tank.



The smithy has been tasked with fabricating some ladders.
