Re: [ATM] Friction and sticking in multipoint mounts

["Don Clement" <clement.focuser@verizon.net>]

Solid machined flexural pivot is a compliant structure machined from a solid
( such as aluminum or steel for example) that is rigid in one or more
directions, but can flex in one or more directions. Attached is an example
of a solid machined  structure that is rigid in the axial direction and can
flex in other directions. I use a similar solid flexural pivot with lead
screws in my focusers that is machined from the solid lead screw material.
There are many examples of solid flexural pivots in commercial use. I also
have an example of a monolithic solid split cross flexural hinge machined
from solid.
