As announced a few weeks back, I will be releasing a range of wagons and carriages as my "3D Print 4 Yourself " range.

Two LNWR brake vans (diagrams D17 and D17B ) are the first now available to download. The design was undertaken using OpenSCAD and the downloads are supplied in STL format.

D17 is the 6-wheel 20T van and D17B is a 4-wheel 20T  van which was christened "Crystal Palace", in consequence of the large number of windows.
Both types are provided with alternative parts to produce either original LNWR condition or with later LNWR/early LMS modifications. In the available photos, no two vans are identical in detail , so, for absolute accuracy, you will need to have a photo from which to work.

Four models have been test built, one of each diagram in LNWR and LMS condition.

Photos (taken under indoor lighting and not very good) are attached of the test-builds which are yet to be painted.
The two LNWR versions are destined for Northamptonshire (the project has been a collaboration with Mike Williams), while the LMS versions are for my collection.

Notes will be prepared to assist with assembly as soon as I have a spare couple of hours but, meanwhile, the following information will assist.

D17 : The van is mounted using a laser cut steel W-iron assembly designed/supplied by Williams Models specifically for this project . The buffer guides (two types) can be printed from the supplied files but you will need either Williams Models or Slater's buffer heads/springs. Other parts required are brass wire/rod, wheels and couplings ... everything else is supplied, ready-to-print. The floor was laser cut from 3mm plywood and the SVG file is included.

D17B "Crystal Palace" : This van is mounted on Walsall Model Industries etched compensation units using Slater's wheelsets running on inside bearings. Other parts required are brass wire/rod, wheels and couplings ... everything else is supplied, ready-to-print. There is a separate "interior pack" file set for this van which contains both STL and SVG files. The SVG files were used to laser cut 3mm plywood for the floor and parts of the minor fittings.  The buffers are a distinctive double-acting self-contained type unique to the D17B and were designed/supplied by Williams Models in brass and nickel silver,specifically for this project.

See http://g3forum.org.uk/index.php?topic=3145.0 for further details and how to access the files.

The next release will be the GCR 45ft 15 ton bogie fish van (BRC&W louvred version).

Good quality prints there John, are they resin?

Mike,

They are of this high-speed PLA printed on the very fast Bambu Lab P1S.

PLA is many times stronger than resin and can bend way beyond angles that would snap resin (and then springs back to shape). Many a time I have (accidentally) knocked a model quite hard, expecting it to have broken delicate detailing but there is never a mark on it.
I bought an Elegoo resin printer and washer/curer 3 years ago (not long after the Snapmaker) but I have never used them.
My feeling is that when FDM printers can produce this kind of result, the messy business of resin is not worth the hassle.
I shall try the resin printer at some stage.

Regards,
John.

Very nice models John and interesting comments about Resin Printers.

I've just watched a review of the Bambu and it does seem a fast, capable 3D printer. I too have a Resin printer that is still in its box...   :-(

Regards,

Nothing's ever Easy - At least the first time around.

The two D17B "Crystal Palace" vans are painted and ready for lettering.
The LNWR version (the darker grey) is as in a 1917 photo of No.626B.
The LMS version is modelled from a photo of No.280361.
There are quite a few detail differences...see if you can spot them!!

The D17 (6-wheelers) are about to have their roofs fitted and (if the weather stays dry) will be photographed later today.

As threatened, here are photos (very quickly taken between showers) of the pair of D17 6-wheel brake vans .... unlike last time, I remembered to straighten the couplings before taking them!

This time, there are few differences between the LNWR and LMS versions.
The LMS van has the later (webbed) buffers and a small hatch door in the end for placing the tail lamp (the earlier arrangement is a hole through which the lamp lens projected from the inside).

The next instalment will be the GCR 45ft bogie fish van, followed by the GCR 4-wheel 18ft fish van.
