Hi. Has anyone designed a way to mechanically rotate their VHF/UHF yagi so
that it can be either horizontally or vertically polarized? If so, can
you
please direct me to a website or whatever. Preference right now for a
manual system, but would also take a look at motorised systems.

TIA.

Do a Google search under 70cM EME. Polarity rotation to avoid Faraday loss
is routine with these arrays- but they are arrays- so the mast/ feedline
plays virtually no roll in pattern- as it assuredly will in a single yagi
when vertically polarized.
