I read long ago that the M35 f2.8 was prone to
grease causing the aperature to stick. When I bought
mine, it had a sluggish aperature. Local repair was
under $40, and the repairman did report grease as the
cause. Hope this helps.

If they are for working on Japanese cameras you should use JIS
Crosspoint
drivers. I got this set and it works very well.

You should be using a JIS Crosspoint screw driver. It is a different shape
from a Phillips and makes it much easier. Like this:

You guys are all sissies. The way I do it is soak the lens in a coffee
can full of ultra fine penetrating oil for a week, and then toss the
lens in the trash. It saves a lot of frustration.
(Just joking, for those who can not tell without a score card)
As a last resort one can drill the screw
With a lot of luck you do not need to fix the lens, it works perfectly.

IMO WD40 and other sprays have little or no place

As a matter of fact I don't even own any.
I use a good quality penetrating oil either on
the tip of a toothpick or in a hypodermic syringe
with a fine insulin needle in
watt range,
which is probably why I've had little luck with
the heat/cool method.

M28/2.8 and M35/2.8 (and M35/2?) seem to be prone to sticky, slow
