Step 11: Making the Measuring Cup
The measuring cup is made out of the "small" tin can and is approximately the same size as the penny stove itself.
1.) There's no need to be too exacting here. Just set the small can next to the penny stove, and draw a line approximately the same height. (Image 1)
2.) Cut off the top (with the dremel, unless you're fortunate enough to own a large tube cutter) so it's close to even.
3.) Sand all of the edges of the cup so it's not sharp.
4.) "Pinch" the lip of the cup so it looks a bit like a spout (Image 2).
The measuring cup can be marked, though I just know by looking how much fuel I need to use in my stove. The ribbed lines around the edge can be used to figure out approximately how long the stove will burn through testing (it will be different for every stove).
I found that this cup was necessary, since the containers of fuel seldom want to pour smoothly, and I didn't feel like having a large fireball in my tent. (Yes, you can use this indoors, with the proper fuel and stability!)
