                                    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
                                    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

                                    Thanks for those additial comments Charles.  I guess the most common rookie
                                    error in applying oil to any part of a camera is to use too much.  It takes a
                                    bit of faith to realize that all it usually takes is a few molecules in the
                                    right place, anymore and it just runs out and goops things up elsewhere as you
                                    I suspect most of that cloudy film thats on those inner lens elements one sees
                                    in almost any 50mm Cintar is the outgassing from the original lubes.  Have you
                                    had any luck disassembling one of these 50mm and cleaning up the inner
                                    surfaces?  I know there are just three elements in there so it seems like it
                                    might be an easy one to recollimate if you knew what the relationship between
                                    elements was supposes to be.  Anyone else with some info on this area?  
                                    I've suspected that this rumor about some 50mm being sharper than others might
                                    have something to do with how much grunge is coating those inner surfaces.
                                    More grunge, less sharp, less grunge more sharp.  I've seen some amazing
                                    transformations in picture quality on other types of cameras just from
                                    cleaning the haze off all the lens surfaces.  I suspect at this point on the
                                    average 50mm the grunge effect may be dominating the quality control effect in
                                    lens sharpness.  Just an unsubstantiated theory on my part.  Something for
                                    additional study perhaps?
