While I now have a track plan for 77 Box Lane I still haven't done any track laying or building construction, mostly as I keep getting distracted by the Welsh slate industry! I did get as far as doing some cobble experiments and I even used some scalescenes.com brick papers to build a small photographic diorama. While the wall looked pretty good on the diorama I came to the decision, when trying to use the same paper for a low wall, that the stones were a bit large and that the lack of relief might be a problem on such a narrow layout, but at the time I didn't have any better ideas, short of using DAS clay and scribing the stones by hand.
About a month or so ago, when browsing in my local model shop, I picked up a piece of Slater's embossed plastikard that looked like it might be a good alternative to the brick paper I'd been using, although at the time I wasn't sure how I was going to be able to paint it to look like Yorkshire stone so it got put to one side.
Iain went and wrote a blog post about the slate wagons I sent him. This in turn delayed Geoff from writing a blog post about his excellent Llangunllo layout. When he did write the delayed post he happened to mention that he'd used RailMatch concrete to colour the mortar course on the building he was painting. The second thing was that yesterday I painted a weathered example of my narrow gauge flat wagon and I decided that the colour wasn't that far away from dirty, smoke blackened Yorkshire stone.
Combining these two ideas led me to paint the embossed sheet as follows. Firstly I sprayed the sheet with a white primer as I found that the acrylics wouldn't stick to it very well. Once that had dried I painted the entire thing using the RailMatch concrete (#2422) to act as a base coat as well as to colour the mortar. I then dry brushed on khaki (Model Color 70.988) followed by brown sand (Model Color 70.876). This was then all toned down slightly with a thin black wash, before the final details were added by dry brushing with dark sand (Model Color 70.847) and black (Model Color 70.950) to simulate the dirty patches.
It was only when I'd finished painting this small sample that I noticed that, according to the sticker on the back, the sheet is for 7mm scale modelling not 4mm scale, oops. Given that I bought the sheet as the stones looked a similar size to those on the scalescenes.com brick paper this would explain why those stones looked too big. The stones on this sheet are actually slightly smaller than on the scalescenes.com sheet being about 3mm, so 9 inches, tall. The sheet might work for a large factory, but I'll try and pick up a 4mm sheet of the same stone effect and see if that looks a bit better sized for walls and small workshops, but at least this is progress... of a sort.
