Make a Geocache Log
Intro: Make a Geocache Log
A friend introduced me to geocaching yesterday. Without much success in finding any caches on my own, I thought I'd hide some instead.
Where better to hide your geocache log, but in a log!
Where better to hide your geocache log, but in a log!
STEP 1: What You Need
You'll need some basic tools and consumables:
- Small log/large branch - look for something an inch in diameter or preferaby bigger. Should be reasonably dry, but not brittle.
- Saw
- Drill and drill bit (12 - 20mm is good)
- Hammer
- Wood glue (I used cyanoacrylate and UHU Hart, but any will do)
- PCB pins (not pictured, they're tiny anyhow)
- Long nosed pliers or similar to hold PCB pins while hammering
- Sharpies (optional)
STEP 2: Cut in Two
Choose a nice log and cut it cleanly in two. For a better result try to keep the cut sharp, square and avoid knocking the bark off (difficult!).
STEP 3: Drill Out Centre
You now have two pieces of log, with a clean edge on one end. You need to drill this out. It's your choice how large a hole you make, I used 16mm and 12mm drills leaving a good few mm of wall. You need enough wall to put the locating pins in later so don't go too thin.
If you keep the drill straight you can make a rather deep chamber. Drill as far as you dare without going through the sides!

STEP 4: Insert Pins
Place three PCB pins in one log. You want to place them roughly equidistant around the log, but don't worry too much about accuracy as the thicker areas will take them better. You may well need to use long nosed pliers to hold the pins while hitting them with a hammer rather than your fingers.
Once in, I found it useful to glue them. This keeps the pins in one piece of wood and stops them getting lost.
I also found it worthwhile to colour code the pins so you can more easily put the stick back together later. Do this before glueing.

STEP 5: Alignment
This is the critical bit. You need to line the two piece of wood up and push the pins into the second piece. You only really get one go, although if you're miles off you might get another. Take a good look at the wood (and ideally test fit prior to fitting the pins) and work out exactly where it should join.
Light force is all that's needed to push the wood together, and the same should take it apart. But the fastening should be pretty rigid once done.
If you find the pins holes a bit loose, a dab of glue might help. You'll have to repeatedly fasten and undo the cache while the glue sets to keep the holes open.
(If you've more time on your hands, it might be worth repeating steps 4 and 5 with one pin at a time. YMMV.)

STEP 6: Stuff
The last bit - insert your paper Geocache log inside a small plastic bag (the wooden cache is not likely waterproof) and go hide it.

I like your use of color-coding the pins so that the parts will fit back together more easily, but I don't think the result would make a very successful cache since one could be literally standing on top of the cache and not realize it.

Well depending on the clue, and where the cache is placed, this could be an effective technique. I've seen some very successful caches hidden in the center of hollowed-out fallen trees, and as they were covered up by tree bark to look natural, the two designs seem comparable. Just be sure when the cache is posted to have a clue or hint, say something like "If you're having trouble finding the cache, look "within" the trees!"

I would love to find some of these!

Note that this cache will not provide a moisture barrier -- the log must either be in a separate container or at least in a small ziplock bag.
I think there is a skill to placing something like this so it looks natural but it does not turn into a "needle in a haystack". It takes no imagination or creativity to hide a fake rock in a pile of rocks, or a fake log in an search area filled with real logs.

PS. It took me a moment to decide whether by "champer" you meant "chamfer" or "chamber". You might think about editting the text to fix the misspelling.
Champer would make a good name for a horse I think.
