Some years ago, a mould used to make the silicone soul on the Apollo EVA boots was snapped up by a collector who then went on to make a very nice limited edition presentation piece making use of that mould. Well this is the cast used to make the original mould.

Made from a composite called "Repro" by ILC model makers and weighing approximately 8 pounds, this cast formed the mould from which Neil Armstrong's boot, and most of the remaining moonwalkers' boots, were made.

Cool and historic in equal measure.

Did they use a system with a suspended core?To allow the extraction of a hypothetical core, it would have to be made of a flexible material, or in two parts, or a collapsible core. The area around the top of the toe would be tricky.

This is just my guess.

A slush-casting process, perhaps? Pouring a certain amount of resin and sloshing it around to coat all the walls, which would probably work fairly well, but would give uneven thickness since the resin tends to pool at the base of the walls under gravity.

Could someone shed some light on this? Any photos, videos, PDFs, or even personal recollections would be much appreciated.

Thank in advance
