I am making my first ever attempt at building from card and plasticard and so far its not going according to plan !
The idea is to build a goods shed based on Swanage, and if that works out then a representation of the Swanage station buildings will follow (slightly reduced in size ) and then the layout will be based on that location. My difficulty is getting the stone effect of the buildings. There do not seem to be any styrene sheets that look the part so I am experimenting with card and plasticard covered with DAS modelling compound scribed and painted. At the moment I have not built the complete goods shed, just experimenting with plain sections of card. The problem is that although the effect is satisfactory for a first attempt, when the Das dries out it seem to shink and cause both card and pasticard to bend slightly, and if I bend it back flat then the DAS gets a big crack in it. The happens with both card and plasticard. I have tried giving the material a covering of diluted glue before applying the DAS but that doesn't seem to make any difference. I don't really want to finish the buildings and then find out I they start to bend.
If I cant get this sorted then Plan B will be to switch the location to somewhere GWR and use some brick style plasticard that fits the location, but I want to stick with the Swanage branch if I can as that gives me a wider choice of prototype locos to use- everything from M7's to Bulleid pacifics.
Any suggestions ?
Am I using the wrong materials? Shall I go ahead and complete the buildings in the hope that being stronger than plain card they won't bend ? Or shall I go straight to Plan B
Thanks in advance.
