Magnetic micro-cache
Does anyone have any hardware suggestions for a magnetically attached micro-cache?
<p>My current thinking is to make something like a certain nameless cache by The Rats that utilised magnets in some indescribable way, but I'm wondering if there might be something suitable that is ready made.
<p>I have considered one of those little magnetic key holders (ones for actually putting a key in, rather than the <a href="http://www.halfbakery.com/idea/Decoy_20 ... >exploding decoy kind</a>), but I think they might be too small, although I guess it would have about the same amount of room as a film-container micro-cache.
<p>Also, any suggestions for where to get a writing implement small enough to fit in a micro-cache? Or should I just tell people to bring their own?

I've used the keyholder to good effect, and it's big enough for a very small logbook and pencil.
The pencils found in TABs and such are good, as they're quite small, or a Parker pen refill makes a small but good quality writing stick.
If you do glue magnets onto a container, make sure they're fairly strong ones. Jaycar sells a nice kit of quite powerful magnets that are worth a look.

I've used and come across good use of magnets on quite a few caches (I can think of at least 5). Echoing what the others say, get good strong ones (although a packet of simple doughnut magnets from lincraft do the trick), and use weather resistant adhesive (i've fallen for that trap, super glue is only super if it stays dry).
May I suggest that you remove the specific cache reference in your post? It's a bit of a spoiler for the unsuspecting finders to be.
As for writing implements, a sawn off pencil or pen cartridge without the barrel) can do the trick.
Magnetic keyholders are good, but won't fit a pen/pencil easily.

Not the kind of detail about [our cache] that I wanted splashed across the forum, but hey thats caching. The cache is more for the views than the thrill of the chase...... Yeh right, who am I kidding.
Just on the magnets, I found when putting the cache together that not all magnets are double sided. Which at times cab be very frustrating as I didnt intend to glue them on. So I guess good glue is paramount.

If you are looking for a cheap source of high powered magnets take a look in the Op shop for some old speakers. When glued inside the lid a peanut butter jar the do a great job.

You also need to consider what you are trying to glue the magnets to. A lot of the plastic containers that are suitable for caches are made of polypropylene (look for a "5" in the recycling triangle symbol, usually on the bottom of the container), which is very difficult to glue. Most contact cements, araldite etc explicitly exclude polypropylene from their list of suitable materials for glueing. Locktite do make a glue and primer for polypropylene, but it is a bit pricey. Instead, you could try indirect methods - eg glue the magnet to a metal base and rivet that to your container.
