My buddy and I decided to take these ammo can saddle bags to the next level by consuming copious amounts of whiskey and making them a little flashier, but still keep that "Holy crap, are those saddle bags ammo cans?" feel. They came out much cooler than I think either of us suspected they would.
2 Ammo Cans
Some scrap sheet metal (steel or aluminum, something with a decent compression strength)
Grinder wheels (cut off, grinding and stripping)
Liquid paint stripper
Nuts & Bolts
Acrylic or Rust proofing spray
These were inspired by another Instructable that can be found at http://www.instructables.com/id/Motorcycle-Saddlebags-from-Ammunition-Cases/
Step 1: Get the ammo can that will work best for you
Army surplus stores sell them if you don't have a couple already. 40mm cans were chosen for this build. Note that 40mm ammo cans in particular have diagonal side rails to add extra rigidity to the box. This was a blessing and a curse for this build. The brackets we fabricated had to be made in such a way as to not infringe on the rail too much, and part of the rail on on one box had to be angle grinded away before it could be mounted flush with the motorcycle. That being said though, the amount of rigidity these rails give the box is significant and will make the box stronger and allow for far less vibration than a box without the side rail. We mounted these on my buddies 650cc Yamaha V-Star.
