Bill,

Swienty makes an extractor specifically for top bar frames (108600 WORLD
EXTRACTOR).  It is a rotating disc upon which the frames are laid on their
sides--bottoms facing out.  The honey is then spun out as it would be in a
parallel radial extractor, except on a vertical axis, and with only three
frames at a time.

It is pricey, but something similar could be fabricated locally.
