    Did the ' Canon Squeak'but now another fault--

    I managed to lube the mirror linkage 'squeak' on my 'gift' Canon A1 after several attempts, following a web-site instruction -- I used a piece of electrical 'Fuse-wire' with a small amount of 'Three-in-one' oil on the tip and touched it down into the correct place, and after several months it suddenly has stopped the 'squeak' BUT now I find the faster shutter speeds are slow and over-exposing -- it seems OK from 1/60 downwards. I have inspected both sides of the shutter blind and NO OIL had leaked -- anyone with any ideas please ?

    Yes. You shouldn't have used 3 in 1 brand glue. Should have used something like a clock oil.

    3in1 is petroleum blend as is Water Dispersant 40 (same company) and both dry out and leave a sticky residue behind.
    TriFlow http://www.triflowlubricants.com/Tri...Lubricant.html
    Clock/watch oil
    Gun oil
    are good oils for cameras.
    Use sparingly.

    Naptha or liquid lighter fluid both work.
    The mirror governor uses resin gears mounted between the mirror housing and a metal plate.
    Dunno why they squeak but they do.

    There's no rubber in there and the gears are likely nylon or another more durable synthetic, not plastic.

    Well, I took some tests using 'TV' and shutter at 1/1000 and 1/500 and the density of the negatives matches so the fast speed must be OK again !
