Hi Brett and Dave,

I'am "assuming" the "2" instruments is really the one ~ same ~ vertical (?),
with either mechanical changes and/or
feedback changes?

As usual (for me), the main spring (phosphor bronze) and the two pivot
flexure assemblys (with presumably 6 total pieces) are of quite some
curiosity.  Of what material, size/s, thickness are you guys using?  Some of
the flexures shown almost look
like cut thin flat spring steel from the photo.

Take care, Meredith
