Make Your Own Pocket Grill for Camping or Hiking
There are folding grills on the market for camping and hiking, but these tend to be quite expensive. This DIY version is cheap, easy to assemble and you can make it any size you want.
Instructables user stvnishere shows us this clever grill design. It is made of two pieces of copper pipe (although you can use any metal), one of which is slightly smaller in diameter so it can fit inside the other. The grille is made from stainless steel bicycle spokes. You will need some basic tools like a drill with a metal cutting attachment, a hacksaw and wire cutters, but the assembly itself is easy enough for everyone. Click the link for full instructions.
