Yes, Foil might be good as well but I think
A triangular low mass frame with two
such wire bearings might be better since
the wire would be easier to get than the foil.
There is such low resistive forces with the wire idea
a frame would be ideal for limiting motions where not wanted.
A truly triangular garden gate like appearance.
Considerable linear forces can be realized
when you are trying to extend the free period
so a lager wire than you might imagine will be necessary.
