Thanks for the info, I'm pondering suitable materials in the model, probably timber or plastikard I think.
In the meantime I have now finished soldering this brute and am now heading off piste into plastikard and bodgery.
First off, here are my scribed door shut lines which I think actually work well enough for a minimum of effort.
You can see my home brewed solebar, required as I completely trashed the brass ones supplied in the kit. I did scrawk out two strips of etch brass etch waste which was epoxied to my styrene items to give them some strength.
The whitemetal axlebox/axleguards supplied by Ken are solid and a bit rough, and after damaging my fingers separating three of the brutes into constituent parts to allow springing with my Peter Korzelius axleguards, I couldn't find the fourth. Sanity struck me, I fished out some spare Slaters mouldings (they are from the milk tank wagon kit) and cut them apart and then stuck them back together with beefed up the springs, job now done for all four.
Next up is fabricating SR style axleboxes,one of the whitemetal ones is under the W iron.
And the buffers, those supplied remain a bit rough after cleaning up, I think I may use some Neil Butcher ones I have in stock, although they aren't quite the right pattern, both types seen here.
I may get some more done today..
