walthers central gas mounting

[jimmygolds]

i just finished buildinding the walthers central gas kit,i mounted the tanks,pump house and pipping on a piece of .40 styrene painted aged concrete, i'm ready to install on my layout,i'm thinking should i just weather the aged concrete base or put some ballast over it kind of like a gravel lot? your thoughts please?

Spreading ballast on it to simulate a gravel lot will most likely be out of scale. If scale is important to you, I would test the idea on a scrap piece first. most likely you will be looking for a much finer material for this application.  Have you tried the usuage of a magnet in a scoop of dirt or sand?  The magnet attracts all the metal fragments out of the pile.  Maybe screen sift the rest of the pile... this is tedious work but might be well worth the efforts.

Try unsanded grout. I love the stuff for this type of application.
