1.) Put your rack pins into the lid (Image 1)
2.) Put your measuring cup into the lid, and put in a coin (my lucky penny) (Image 2)
3.) Place the Penny Stove into the measuring cup upside down and put the Wind Guard over the whole rig. If you made a hook for holding your rack, this can also be put in at this point. (Image 3)
4.) Lock everything in place by sliding the rack over the whole unit. (Image 4)
That's all there is to it! You're ready to go camping!
As a final touch, to make your rig look more "professional" as well as extend its life, here's some great tips from some of the comments:
