Hi all,
I've been massaging this new Argus C of mine back to life. Last night I used
a trick on the lens focus helix that some of you might find handy at some
point.
The grease in the focus helix on these old cameras typically congeal and dry
out making the helix almost impossible to turn. On my C the lens would
unscrew from the body before actually focussing.
What I did was take some light weight machine oil (sewing machine oil) and
with the tip of a jewelers screwdriver I dabbed the tiniest bit of oil on the
edge where the inner and outer helix meet on the back of the lens. Just screw
the lens in and out a bit and you can see what part is moving with respect to
what other part and thats the line to dab the oil on. I then just slowly
worked the lens in and out which gradually got the oil in to re-emulsify the
grease. I dabbed a bit more oil on as I went along and after slowly running
the lens in and out a hundred times or so it has regained a nice viscous but
not loose focusing feel. This same trick can be done with some Automatic
Transmission Fluid Type F. This is really thin stuff and will work its way in
and re emulsify the dried up grease really well. The trick is to start with
as tiny an amount as you can, it seems like it couldn't possibly do anything
but 4 or 5 micro drops around the diameter and running the lens in and out
just a few times you will start feeling the difference.
Good luck,
Carl Turner
