Adding locks to ammo cans
You can buy ready-made parts to add a lock to an ammo can. But these are generally just a big bolt that fits through the existing hole in the can's latch. The diameter of the bolt severely restricts the size of the lock you can use. Most of the ready-made systems I found required a lock that wasn't much sturdier than those on cheap luggage. And the small diameter bolt means attaching the lock is sort of fiddly and delicate. Not so good when your hands are cold and muddy.
So I tried something different.
All the components you need to lock up an ammo can. Just drill a couple of holes in the can and attach a stainless steel U-bolt. I bedded the fasteners in clear silicone to prevent rust and leaks.

The latch on the can makes a pretty sturdy hasp. Just cut a slot to accomodate the U-bolt. I used drills and files to make the hole.

Want to secure a shovel, axe, or something similar? Get a piece of steel cable and form a large loop in each end. Drill a hole through the handle of the tool. Pass one loop partially through the hole. Pass the second loop completely through the first and lock it to the ammo can.
This won't thwart a band of sophisticated pulaski pirates. But it will keep an opportunist from just grabbing your stuff.
