I am planning a bit of camping soon and last year I did not get around purchasing to a stove for cooking.
I was not comfortable storing propane or butane in my car where I was sleeping. So, I decided to do some research.Mark Young in Nova Scotia has several good videos.
I needed a base which raised the hot box to allow air to flow from the bottom and prevent coals and ashes which may fall through to the ground.
This is an IKEA Ordning food warmer which is designed to work with tealights. It raises the fire box about 1.5 inches and provides protection from falling coals and ashes.
With holes in both pieces I just needed to connect both pieces.
I had bought 2 stainless steel drinking straws so I combined those with lengths of wire hangers cut with my home pliers and a little persistence.
