Greg,

You have the correct sequence. It's actually a 'piece of cake' to do. As for 
the positioning of the aperture scale, it's been a while since I've done it 
but from memory do the following: Turn the large knurled bottom ring 
anti-clockwise (this is the large ring above the one with arresting screw), 
then turn the lens into the desired position and retighten the ring. Don't 
forget that the Focotar 40/2.8 can be pulled down (gently) so that the 
aperture changes become stepless. Found the best setting for my Focotar was 
about halfway between f4 and f5.6.

Feel free to email me with any future questions you may have concerning the 
V35.
