[R-390] Oldham Coupler Idea

[Jon Schlegel]

Hi All,

I was just looking at the three Oldham coupler pieces and the effect 
that the antibacklash spring has on them.  The single spring has a 
tendency to put the two shafts into shear which would seem to create 
an unnecessary radial load on both shafts.  The gears on the RF 
module have two springs.  Why didn't the coupler designer add a 
second set of pins for a second spring?  I was thinking of adding a 
second set of springs myself.  Any thoughts on this?

Regards,
Jon
