Re: tapered secondary form?
Tristan,
Some time ago, someone posted a method to heat weld two containers
together. He just poked a hot soldering iron through the two container
bottoms numerous times, and said it made a strong joint. Best to use avoid
breathing the fumes if you try this. Another method would be to use a
handful of nylon screws and nuts.
