If this isn't a joke, What is a turnbuckle first off? further what's a revolving turnbuckle and
what part of the tape frame are we talking about?
Turnbuckle - the bit attached to the spring at the bottom of a tape frame that the tape runs through. Usually a solid moulding that forms the bottom of the large 'W' formed by the tape. If John and Martin (and Brian?) have come up with a revolving version (I have to assume the pins that the tape passes over are the bit that revolve) then that removes a potential sticking point in the tape path...
