Digital cameras (Piano Action)

[Joe And Penny Goss]

Hi Don,
I love the hex design. if you want stiffness with the least weight a 3/32
inch hex shaft is as strong as a 1/4 round and weighs less. The spline needs
to face the direction of the force to take advantage of the hex shape. Above
mesurments are approximate.
