Hi Chris,

Below Chris you mention below how "the whole setup can be quite compact".
If a "SNEAK PEEK" (of info) is allowed :)  How small or
compact could the variant LIGO "X" plates size and/or rolling wire
pivots separation be?   :)           ....the natives are growing
restless....

Take care, Meredith
