PVC pipe cache
Simply put, a PVC pipe cache is a cache made out of PVC pipe!
- Easy to make
- Cheap, especially in quantities
- This type of cache probably runs a higher risk of being mistaken for a bomb because it is made from pipe, and people think pipe bomb!
- Can be hard to open if reclosed tightly
- Can leak if not reclosed tightly
How to make one
Where you get the materials
These materials can be found in almost any hardware that has plumbing materials.
Materials you need
- Here are the materials you will need
- First you need to choose the size of the pipe you want to use. This will probably be dictated by how much money you want to spend. 3-inch pipe makes a decent-sized cache. Pipes are available in almost any length. PVC pipe is white plastic, and can be cut to size by almost any saw. A Hacksaw is cheap and works well. You can make many caches from one pipe by cutting it into shorter lengths.
- Next you need to choose two endcaps for each cache you want to make. Make sure you choose the right-sized caps for the pipe you got.
- For each cache you want to make, you need:
- One plain cap to seal one end of the cache.
- One cap that can be unscrewed, usually called a "clean-out"
- Now you need to get the glue and primer. If you don't see it next to the pipes, just ask an employee for PVC cement and primer. They come in small metal cans.
- Some type of saw to cut the pipe to length. You can usually find a hacksaw nearby to the pipes in the hardware store, they are cheap and work well.
- Buy all the materials listed above.
- Cut the pipe to the length you want for your cache. Be careful to make as square a cut as possible.
- Clean all the "sawdust" out from the end.
- Scrape any labels off of the pipe where the seal will be made to the caps. You should have at least an inch on each end of the pipe that is clean and free of any labels.
- Dry-fit the three pieces of your cache (the pipe, the cap, and the clean-out) without any glue to make sure everything is good.
- Open up the primer can and use the brush that is built into the cap to paint a band around the very end of the pipe, about an inch wide. Go around and around a few times to ensure good coverage. Depending on the size of your pipe, you may want to wipe some excess on the endge of the can before you start painting, or you may need to double-dip for larger pipes.
- Repeat this process with the cap, but paint the inside of the cap.
- Allow the primer to dry (30 seconds or so)
- Open the cement can and spread a thin, uniform layer on the pvc where the primer is. Do both parts
- Press the two parts together using a twisting motion. Only twist one way, not back and forth.
- Hold them together tightly until the cement sets, about 30 seconds.
- Repeat the proceedure with the clean-out end. Open the cleanout and set the center section aside beforehand.
- Make sure you didn't get any cement in the cleanout threads.
- Thread the cleanout plug into the cleanout and then paint, camouflage, whetever. Do not get paint or anything on the threads, leave them white and clean.
- Fill with swag, mark clearly as a geocache, and place well!
