I am just starting down the path of making my own Foster's pot. I plan on cutting it so that it holds 20 oz or so.
I had a few things to ask about regarding keeping them from flexing too much and causing a pinhole leak that I have seen some people say has happened to them.
First, cutting the can down a little shorter, and adding the top from a tuna can to it, ala Sintax77's youtube video...would that add some rigidity?
Second, how about the wrapping of kevlar cord or fiberglass string around the middle of the can for picking it up when hot...if the cord wrap was 2+" in vertical height along the can, would that maybe help too?
And third, has anyone tried to mush (scientific term) one Foster's can into another one that is cut in half? You could wrap the kevlar cord around at the seam. That seems like it would add rigidity as well.
Thanks for the help!
