After quickly fixing my OM-10 which the camera shop jammed the lens
mount on, I moved on to the free parts OM-10 which he gave me, hoping to
find the sticky mirror, and use it as a practise run...
Initially the body appeared dead, since the mirror only flipped up part way
when the shutter was fired. Here's what I found:
-this early OM-10 has a metal bottom plate (s/n 352xxx), vs plastic in my
newer 2496xxx model.
-the battery check and self timer are dead, which John H. mentioned recently
-the shutter could be "reset" by moving a small lever under the bottom plate,
after which it would fire normally 5-20 times before sticking again, leaving
the
mirror half up.
-at this point, I found awful oil on the magnet problems: in "B" the shutter
would take about 1 sec to close after lifting my finger from the shutter. This
was what I was hoping for - a perfect candidate for my test.
-I successfully removed the bottom of the mirror box, and found the tiny
sticky magnet, hidden under some flexible circuit, which had to be pried
loose.
-I held the magnet contacts apart, and slide a sliver of thich paper soaked in
brake cleaner (degreaser) in between, and repeated several times.
-Afterwards, the sticky magnet appears to be gone, but the occasional
shutter/mirror jamming continues, and of course, the self timer/battery check
still does not work. Shutter and OTF meter appears intact in all modes also.
I think this could be made a workable last resort body, if I can determine why
the shutter jams. At this point, I'm not sure if it's mechanical or electrical.
