PVC Cement Get Here Choosing your PVC – The size of your capsule is really up to you. I chose to use 3” pipe and fittings – which is almost big enough to reach inside of, but not quite. If you are storing larger items you can choose a larger pipe size. Similarly, the length of the capsule is up to you. All that really matters is that you use the same pipe and fittings sizes so everything fits together. PVC is a lot like adult Legos. You can make almost anything from the simple building blocks. There are a few different ways you can configure a capsule using PVC. By using a slip cap on one end and an adapter with threaded plug on the other, we can create a water-tight container that won’t be a pain to get into when we need to.
1. If you’re cutting your own PVC, mark your pipe and go slow. Use a hack saw or miter saw to carefully cut through the pipe. Use a file or sand paper to smooth down any rough edges or burrs. This will help your fittings slide on easily.
2. Dry fit your container by sliding the slip cap on one end and the female adapter on the other. The fittings should go on without too much difficulty but still fit snuggly. Screw your threaded plug into the adapter end. If everything fits nicely you can begin to cement.
3. When you’re ready to cement, take the capsule apart and apply cement on the outside of one pipe end and on the inside of the cap. While the cement is wet slide the cap on the pipe and give it a quarter turn. This spreads the cement out and creates a nice seal. Hold it here for about thirty seconds while the cement does its magic. Do the same for the slip side of the adapter, but don’t cement the plug. This needs to open and close freely. When your capsule is glued give it an hour or so to dry.That’s it! Now it’s time to add the supplies. If you’re using the capsule as a survival cache, think about things that you will need but might be hard to come by in a doomsday scenario. Some people even pack things they won’t necessarily need, but may come in handy for trade. When your cache is packed, screw on the plug so it’s sealed tight. When choosing a place to hide your cache, consider ease of access. You want it to be somewhere that you can find easily but that others can’t. Some choose to hide caches in their own backyards, while others may travel hundreds of miles to strategically place a cache. Wherever you decide, make sure you record the exact spot on a map and if possible take down the GPS coordinates. This will help you find your cache quickly and easily in the event of an emergency.
