Hi all,
I have a couple of Arca-Swiss Monolith function carriers which have issues. I think the focus drive mechanism is the same as early F-Line models if anyone reading has experience of these.
The first one won't tighten onto the rail properly. No combination of turning the focus drive or locking knobs seems to clamp the carrier to the rail. On the second one, it will lock securely but turning the focus knob does not make the carrier move (it slips).
Short of sending these back to Arca-Swiss (and a potentially very long wait), does anyone have experience with these things and their likely causes?
I have taken the knobs off the drive and I see a couple of springs which may be faulty but there's not much to it really. Does anyone know what these springs should look like on a good carrier? As I mentioned I think the focus drive mechanism is the same as the earlier F-Line carriers where there is a distinctly separate metal bar which is squeezed against the rail block when locking the focus to provide friction.
I'll try to post some pictures tomorrow of what I've got.
Any pointers gratefully received!
Thanks,
Phil
