This will be the last Evil Geocache article for awhile. I’ll come up with some better ideas, but for now this will be all.
First we wrap the container in ordinary plastic wrap which is found in any grocery store. We do this because the container is with all kinds of materials during the process of the cache building. When completed, the wrap is removed for disposal. It is important to keep the curing material away from the container while you are doing the build. Epoxy will bind to just about anything. If the epoxy should leak the container, you might damage it trying to pry the container loose.
Because of the over-hang on the container, it is impossible to cast around it for our purposes. We are making a fiberglass shell for the container, but we want to get it out of the shell when finished. To do this, we trim the container with clay, which is easily removed once the shell is complete. Once again, the artist clay used is found at many craft stores. I recommend a curable clay because the non-curable ones are cut in oil which might interfere with the epoxy curing process.
This time we’re not going to make a shell over the container out of fiberglass. Instead, we’re going to use Kraftmark Terrain Putty to make the entire shell. It is easily molded around the container and will set-up in 3 hours. Once hardened, it’s easy to carve or sand the cured putty to fit any container you need to place into it. It’s also very light and strong.
Once again we use Kraftmark Stick Putty to secure the rocks to the structure. We’re going to use bigger rocks this time, which will make the job go faster. The rocks I use are common shale, which is abundant in Pennsylvania. Shoot, you can’t dig 2 feet around here without hitting the stuff. Make sure the rocks are washed and clean.
We add more rocks:
The Stick Putty sets up in five minutes, so have everything ready before activating it. Although it gets hard quick, full cure will need several hours.
The rock pile is ready to be placed. It’s heavy enough to fool any casual onlooker, but obvious to the trained geocacher. Turing it over we see:
A hollow compartment ready for a cache.
