Pugsley
Western Thunderer
As some as you may have seen, I have entered the scratchbuilding competition in 'the other place' with a plan to build some of the Cargowaggon twin sets, as seen here:

I have been using Alibre to design all the bits and pieces for the project, starting with the buffers, both inner and outer, and axleboxes. Both of which I luckily managed to find drawings of out there on t'internet, which was a definite bonus!
The components for casting have been drawn out at full size, and will be shrunk down to 7mm scale before being 3D printed. I plan on having the axleboxes and buffers lost wax cast in brass, as these items will be functional, I'll cast other detailing parts in resin, at home.
Progress so far:
Axleboxes:
The text on the axleboxes does stick out too far, but this will only be 0.2mm proud once scaled down. It might not come out, but I thought I might as well push the technology, to see what's possible
If it does come out too big, I'll rub the masters down gently, before casting, to reduce the effect.
Outer buffers:
These are designed to be completely self contained, with the head screwing into a 10BA nut in the housing, so nothing projects from the rear of the housing, so nothing has to be compromised to accommodate it.
Inner buffers:
These work in the same way as the outer buffers, being completely self contained.
And last, but not least, progress so far with the chassis and superstructure of the wagon itself:
Progress has been fairly rapid up to this point, but it's starting to get more involved, so will likely slow down a bit from now on. The CAD package is proving very useful for this exercise - it's good to be able to test the look and fit of parts, in situ. It would be a lot trickier if I was just working in CorelDraw, as I have for previous etching projects.
I know one thing, I should have started my etch designing with these, not the TTA tanks, as this is proving to be a lot more straightforward. It's all good experience though, watch out JLTRT
