The results of my labours with Google SketchUp have finally arrived from Shapeways, detailed in previous blog entries.
This time I have received a complete GWR Catte Train comprising 2 x Large W1/5 Cattle Wagons, 1 x Medium W2 (Outside Framed) Cattle Wagon, 3 x Small W3 Cattle Wagons (this was a bit of a cock up copying and pasting as there should have been 2 of each! 
), and to tail them off an AA16 Outside Framed Brake Van. Each of these were drawn in SketchUp in separate files, and a new file built containing all of them built by simply copying the relevant wagon from it's own file and pasting it in the combined file, the resulting combined file was saved as an STL file, and NetFabb used to correct any errors using the default fix.
In addition to the wagons, I had also incorporated some sprues of springs and axleboxes for both the Cattle Wagons and the Brake Van. These were quite fine, and if I'm honest I was unsure whether they would work - they did, although all bar 2 of them had become detached from the sprues in the Shapeways cleaning process or in transit. The axleboxes are a mixture of Grease and Oil, and for the Brake Van were drawn as 4'6" long with J hangers, and for the others 3'6" long.
Below are a series of photo's that show the complete order (which cost £37.50 incl post - which I think was pretty good for 7 wagons!)

Last one illustrating the recesses I've drawn into the model to facilitate the use of the 2mm Scale Association's RCH W-Irons (part 2-312) :
W2 Outside Framed Medium Cattle Wagon :
W3 Small Cattle Wagon :
AA16 Outside Framed Brake Van :
This was drawn complete with the bench/box ad floor at the verandah end, and incorporated the brake standard. Unfortunately, the handle of the brake did not survive the journey so will have to be replaced with wire.
All of the wagons were drawn with holes for the buffer shanks, and a central slot to accomodate the draw hook. Additional holes were drawn in te solebars for the horse hooks (except on the W2 which has a wooden solebar, the plating detail on which isn't really visible in the photos but is there). The Brake Van has 0.3mm holes in the solebar and body side to facilitate fitting of footboards and handrails, which have come out but will need to be opened up as they look significantly smaller than the 0.3mm I had drawn them at - perhaps they still have supporting wax in them.
That's all for now - I don't think I'm going to get too bored over the next few weeks now!
