Chuck, As I recently posted I bought the circular clamp with Arca Swiss clamp.
As I stated I can fit it to the top of my Manfrotto ball head. However I had
totally forgotten about getting the pivot point central with the nodal point of
the camera lens. By offsetting the supplied Arca Swiss plate I can just about
manage it but really I need a longer plate with an Arca Swiss groove cut into
it ...BUGGER!!!

Subject: [OM] Time to revise the pano hardware plan
The other day I said I could use one axis of my macro cross-slide to resolve
the tripod socket off-center problem on my E-M5. The other axis can take care
of adjusting the no-parallax-point.
All well and good until I put the rig onto my tripod on top of the Manfrotto
410 geared head. I had intended to use the level on the geared head to level
the tripod itself and then use the head to control the stepped rotation for
panos. No go. I had failed to notice that the camera mounting plate on the
geared head is nowhere near centered with respect to the vertical axis of the
tripod.
Back to ground zero. I pulled out the original Manfrotto 3030 3-axis
(non-geared) head that I bought with the tripod about 20 years ago. It
*appears* that the mounting plate there may actually be in line with the
vertical axis of the tripod. The problem is that I don't know how to verify
that it really is aligned. This is what it looks like.

Anyone have an idea how to tell if the center of the QR plate on top is really
directly above the center of the tripod post? I guess I could suspend a plumb
bob above the screw on the QR plate and see if the plumb bob stays centered on
the screw as the whole assembly is rotated.
