Many thanks for that, I've ordered the book! I have amended the files on Thingiverse to now include NER versions without the lifting beam and with NER builder's plates.

Yes please, I'd like to see that. Were the Tyneside Electric ones double ended too?

I knew I had a book somewhere.... I found this today in my collection. This 1961 publication explains that snow is not just snow. It has a most extraordinarily variable set of physical properties that must be a real headache to deal with. Its specific gravity, cohesion and plasticity vary massively. Plough design is a real science. Fortunately no indoor layout has to deal with these factors. In the book is an image credited to British Railways of the other side of BR Built Snowplough S3, with lifting jib detail. I upload it here as it's different to the images in Southern Wagons Vol 4. I have learned from it that the hand wheels were opposite to each other, which I didn't know before, and I have amended the positions on the files on Thingiverse. Jonny

Ordinary wagon wheels just pop straight in.

It looks like the Skunk Works had a proto Dalek. 3D files are free to download at www.thingiverse.com/ironmink/designs I'm very grateful to John Isherwood for making the decals available. Compliments of the season. Jonny

Mike, I agree 100%. I draw at full size but ensure all details will scale to at least 4mm/ft. This means some dimensions are exaggerated to print on a resin printer at optimal orientation to produce resilient models. Every design has several iterations before publication to ensure they work. Drawing at 1:1 scale in millimetres is waay more convenient than working in fractions of millimetres, the 3D slicing software allows the scaling to suit models. Jonny
