Interesting topic. Even though I live in an area where people feel totally comfortable leaving their doors unlocked, I still think it's better to be safe (pun intended) than sorry. Not to mention some of these safes look almost as cool as the contents they'll hold!
This is why you don't buy plastic safes: [youtube]http://www.youtube.com/watch?v=BRTnJVwYkJs[/youtube]
-10 for buying a plastic safe in the first place +100 for the effort in getting it apart -1000 for the crazy soundtrack/sound effects
Massively useful thread. We are just about to vacate a rental property where there is a cheapo digital 'hotel style' safe - locked (empty) and where I have no idea of the combination. A strategic 'hit' later and it's open - so one less thing that the bond might be withheld for!
If your slab is susceptible to moisture your going to be in trouble with a metal safe. Considering most shed slabs are only 100mm-150mm thick at the most that leaves the rest of the safe exposed to the underlying ground? Boxed out and concreted to avoid this will form a natural moisture catch for rust to occur. Personally i would just leave yourself the option of changing locations by bolting it down to the ground. Without a sledge hammer or powered grinder to remove(And thats a hell of a lot of noise) it ain't going nowhere. Sheds are great first entry attraction points to for a crime as they naturally contain power tools and can be accessed easily without disturbing the occupants of the premises. I would avoid the location all together. REDBACK
In ground concreting requires the inclusion of a waterproofing substrate to the concrete mix so this would reduce the rust issue somewhat i gather.
