This as been an absolutely brilliant read and build. I would love to have something like yours on our new line, but unfortunately my building skills come no where near to what is so expertly done. Don't think for one moment you are not by the way. :thumbright: :thumbright:

Building Ginnerbeck viaduct: Appendix

Thanks for all the positive feedback. This includes praise for the quality of the stonework, and I really didn’t discuss this aspect at all just starting with “I used standard RLR building sheets”.

The basis of all the stonework is the JigStone system.

My moulds are maybe 20years old and up to this project pristine. One mould had some rubber pulled off from a mortar line when demoulding last week. Although initially expensive they last and last. They are still available from https://modell-werkstatt.de/jigstones-2 which is a German site but has a Union Jack to click on to translate. He also has lots of other obscure things. This year I got a very nice cast brass weather vane for St Luke’s Church. Payment was easy, it arrived 1 day later.

I did get a set of brick moulds as well but I found the smaller distances between mortar lines made jointing the blocks much more time consuming. They have been used for chimney stacks.

Fit a long time I used the blocks as intended, assembling individual blocks into quite large structures such as Rylston station. BTW the station is self-coloured U-pol not painted.

However the blocks are quite thick and wasteful of resin. I noticed that pattern of the stone work in the building walls of one Major 16mm supplier was similar to the JigStone repeating pattern. I wanted to modify that building to suit the Rylston Light better so I made a sheet master from JigStones and made a mould. The resulting sheets match the thickness of the building supplier’s kit.

So the viaduct is basically a JigStone project. As it is it required 245 separate cast pieces; I cannot calculate the number if I used the original block size. But the quality of the stone-work is definitely JigStones. I would encourage anyone to buy JigStones; they work well, thy last well. And they can be adapted to local need.

I have even adapted the stone-pattern to another use but that is part of the teaser of the cunning plan. After all these lead-in teasers it better bl@@dy work.

Jig-stone, love it, when I did 00 a number of years ago there was a similar system, though designed for plaster, and you had a whole package of parts, and when moving up to G/16mm I looked for something similar but couldn't find anything, but this is it :D :D :D

My first build was a small PW hut, now designated for a quarry office, cast from resin plaster from Gedeo. The moulds work well in most casting materials. Cheapest is ordinary cement with fine aggregate and I have cast some dry stone walling in that. It doesn’t quite hold the detail as well as resin or resin plaster, and take a while to cure.
