Maybe rig up a pouring bucket like they have in foundries - a bucket with a pouring lip, hinged within, and suspended suspended from, an inverted 'U' shaped bracket?

I am confused and if I caused the confusion then let me apologise but the weight of the polyurethane is 6.5 litres or 14.5pounds, so where did 65 pounds come from?
Lynn,
The gaps around the bottom of the mould as superfluous to requirements, the vertical pieces of steel that form them, are only there to retain the flat strip that forms the outer face of the tyre in place and at the correct angle. These vertical pieces have been machined at an angle of 5 degrees on their top face which is the correct angle for said face.
The thin metal sheet, that gets wrapped around the mould and forms the outside diameter of the tyre, is held in place by long jubilee clips. One at the bottom of the mould, that seals on the area shown on the picture below (marked with a red arrow) and one at the top the seals around the top cover.
The sealing area is pretty thin but as it has been machined I am confident that it will form a good seal.
I hope that it explains it or at least my theory.
Jon
