Hi, Doc:
        Multi-section mold with provision to hydraulically lift hemi off
the male portion of the mold as soon as the casting has sufficient strength
to hold shape - so the casting does not begin to shrink onto the male and
start crazing. The hemi is lifted just a tad then held in position until
finally 'cured'.The hemis are truly gorgeous when finally polished, sealing
edge machined, and the assembly set into the polished, anodized,window
ring.
