I'm making a Terry Pratchett inspired model railway (the Ankh Morpork and Sto Plains Hygienic Railway to be precise).
I'm chopping up all sorts of stuff to make it Pratchett like. Yesterday I made a coach for transporting Trolls, and part-converted a loco, and I also started making a Pratchett-like building (think London pre 1666 with added grunge and smellier) - I'm making masters for building parts and I'll try casting them in resin.
I'll put some photos up.
And if anyone could aim me at some OO scale models of trolls, golems and dwarfs I'd be very grateful. Either that or I'll have to learn to sculpt, and I ain't that talented!
