Work continued on the small Nelson steam plant in order to test techniques for the matching, but much larger, diesel house. The large windows begged for some simple interior detailing. Also added were external cooling pipes, a chimney and up right tanks to match my 1970 era.
Instead of sand, how about painted sandpaper? You can probably find a grit to match your stone size, and a piece of paper is a lot easier to glue neatly than a pile of sand. It worked for me, but glue it on with water-based glue, and if you don't like the results, pry it off and you can still use the real sand.
You don’t need to glue a “pile of sand.” Spread a layer of white glue, sprinkle the sand over it, let it dry, and voila! This is how I make my coal loads with black sand. Might even be easier than cutting a piece of sandpaper to perfectly fit.
Very nice! Are those the Alps-printed window muntins?
yep. The larger vertical mullions and frames are laser cut. The narrower (1") mullions are ALPs printed. On the steam plant, and on the end walls of the diesel house, the window elements are assembled individually and glued into the window openings. However on the much larger diesel house side walls, the walls will be laminations of three laser cut pieces and one contiguous ALPs printed Mylar sheet. This is quite a registration challenge and the Mylar window sheet is being reprinted with a 0.994% scaling factor in the long dimension to accurately fit to the laser cut walls. Over the 17" length of the longest diesel house wall a scaling difference of a few thou is quite noticeable in the alignment of the last window frame and mullions (vernier acuity https://en.wikipedia.org/wiki/Vernier_acuity). It was also a colour-matching challenge between prototype photos, the spray painted laser cut pieces, and the double struck CMYK ALPs-printed Mylar, thankfully now behind us.As expected this is a very interesting project pushing me to learn all sorts of new stuff.md
