I just unpacked my NEW LEE pot, and casting with it was uncomfortable with the new height of the opening, preferring the 2" of my existing pot. So I cut a piece of 1/2" MDF to fit, nailed in three brads and found an empty salmon can of appropriate height. The can sits against the brads to catch drips, and fits OVER them to be a rigid base for my molds when casting. It works for me: YMMV.
