Right, didn't sabotage the aperture ring then, and have relubed the focus helix with S10, just the right amount of resistance.
Followed the pdf linked to above to the last page because the aperture ring, typical of the species, had a horrible feel too from dried up old grease.
"To re-lube the ring, first remove the index pin marked
here in yellow. Next remove the lock ring screw
shown in green. The ring will now unscrew and the
two halves can be separated. " - Did that, and the two halves now can be turned round and round, what they do not do however is unscrew from each other. It's as if some threads need to meet except the halves haven't moved out of vertical alignment yet, they are as when the two screws were attached. Someone with an idea?
Edit. Ah..."ring" Will try and get that ring off, tricky to grip.
Further, I should have paid more attention the the index pin screw because it should sit in a slot and it isn't immediately apparent how to make it stay put in a slot, so can't abandon ship now and reassemble. If anyone has relubed the aperture ring of a silver Jupiter 8 it would be interesting to hear of their experience with this. |
