Ammo Boxes for Panniers




I am an avid commuter and I wanted to add panniers to my bike, but with a twist. I was inspired by the use of the ammo box for the cover of "Final Doom", and Zapwizards computer mod. I had a few of those ammo boxes lying around, and I figured they would make great panniers.

Step 1: Gather Materials

I did this on a whim, so I did not plan very well, or buy the best supplies.

There was only one place to get stainless hardware in my small college town, so I had to make do with what I had.

I bought some stainless machine screws(needed bolts), nylock nuts, and 1/2" clamps.

I had an old inner tube lying around to use in the clamps to prevent squeaks.

Finally you need the ammo box they are commonly refered to as 25mm ammo box(or can).
They are made of heavy duty plastic, open at both ends, have a rubber gasket, a removable divider for the projectiles, and they should be waterproof.

Step 2: Anti Squeak

This step became useless when I found out they make clamps with rubber dampeners already installed.

I wasn't into measuring so I just guesstimated with a lighter.

Step 3: Mounting on the Rack

I just eyeballed it.
I left enough room so my feat didn't hit the ammo box.

Step 4: Fully Mounted

Mount both sides otherwise it will lean one way or the other.

Step 5: Load Them Up

Plenty of room for a change of clothes and my school books.
Too bad it was way heavy.

Step 6: Try Different Boxes

I did this for the photo op.

    you should rig a ammo box to the front end for a counter Waite to keep it from tipping

    I'm not sure; but a quick google says 12lbs.
    When I had them loaded with my books and clothes for the day the bike was very back heavy and would tip back when I wasn't on it.

    Hello, I haven't checked this in years.
    I don't recall what the brand was, I picked it up at a bike shop ages ago. Part of it broke off and I eventually only used it to hold a u lock

    I know the smaller ammo cans are made out of metal, but what are the 25mm ammo cans made out of? Great idea and instructable!

    Hello, some sort of plastic/nylon. It's very sturdy and watertight at least until I drilled those holes.

    A very tactical looking bike. Looks ready for any mission.


    I like that these are low and flat enough to easily swing your leg over. The trouble with many DIY bike cargo carriers is that you have to be a ballet dancer to mount & dismount with the bike loaded up. It's hard to look cool when you are in a heap on the ground, under your bike, with a foot snagged on the milk carton. ;-0


    I really like these. There are some lighter ammo & boat boxes on the market. Not as sturdy, but perhaps more practical? I've got commercial panniers, but I think one of these would be a good addition to the home-made dog stroller.

    This is a totally rad idea. See if those motorists give you any hassles now!

    awe, I should have known people were wize enough to make such a thing, my instructable is useless. You did a wonderful job, looks great. Perhaps just go with smaller ammo cans next time seeing as it was too heavy? Cause it is really useful. I would like to figgure out a way to make it secure yet easily detachable, hidden clamps or something. Anyway, great job! thank you for sharing.

    Share what you have anyway. Even if it's duplicate. I think you can buy replacement mounts for some of the more fancy panniers, and then mount them on ammo boxes. Give it a try and make an instructable.

    Good idea sluttyduck, pity they were heavy. I suggest for commuting - light shopping a pine wood box with sides 6 inches (15cm) high on a plywood base. Style, paint and decorate how you like, fit reflectors at rear, maybe provide mounting for a tail lamp. You can bolt a telescopic pump holder to the front, or a battery carrier for lights, hang a tool box or water bottle from it. Size it to suit a standard briefcase for school or work use. Takes a loaf of bread and a carton of milk with room for a few other items. You can even make a tonneau from vinyl if you wish. These used to be common in the small Aussie town I spent most of my teens in. I made one the other day, but should have made it a little larger.

    They are 25mm high explosive rounds ammo boxes(cans whatever).
    They are plastic, or possibly some type of nylon, they also have a gasket at each lid. According to this site they're 13lbs!
    I thought about taking a small grinder or something to grind out the inside to shave some weight(there's a lip in the middle), and they're pretty thick.
