Here is what a fellow made and well photographed so I wont re-invent the wheel,I will link to this so you can see construction.

I like it runs on twigs and tiny branches,almost always easy to find.

===============================

This is my version.....

I needed 4 screws,drill,tin snips,2-43 ounce Yuban Coffee cans,2-28 ounce spaghetti sauce cans and 2-14 ounce vegetable cans.


The coffee can has a lip around the top.I cut the bottom off 2nd can and its screwed to the lip of stove can, on the top to make the lid.



I filled mine with sand instead of perlite because I had it and you tubes say sand keeps sides cooler and figure added weight will make it more stable.




So off to amazon for a stove grill and pan,

grill was 5.75

===================
Cost ten bucks and is a FUN 45 minute project (Kids would love it!),you could skip the grill and its free,or you can buy one for 82.00 or 115.00 on Amazon
