Hello all- I'm scratchbuilding an open-topped water tower in HO scale. I had originally just wanted to build a plastic kit but it looked thoroughly cheesy so I just used the kit as a template for the wooden one that I am building. My quandry is this- how to make the tank? I'm using 1/8x1/16 balsa, stained with Jacobean stain so that it looks like a water tower (instead of looking like a fifty cent glider). I have the structure to hold the tank, I have the platform, but the tank itself is looking tricky. Right now, I'm trying this: using an old juice can as a form, I'm building the outside wall of the tank. Once it is completely wrapped around the form, I will wrap it in plasticene, remove the form, glue it down to the platform and fill it halfway with Envirotex. I'm hoping that the plasticene will keep the tank intact for long enough for the 'tex to harden, which will keep then tank glued together forever. I'm worried about the envirotex leaking out and/or getting on the outside of the tank as it dries, though. Any suggestions?
