Broken Screw

In the process of disassembly, to replace a messed up Fresnel screen from a recent purchase I hit a snag.

The screw that holds the Film counter Disc in place sheared, as soon as I attempted to remove it (I know it's a LH thread and they are "delicate").

Past few weeks I have removed about 6 or 7 without issue. However, my question is, how to remove the threaded part of the screw which still sits inside the Film advance Mechanism.

Do I need to remove the whole thing from top to bottom maybe ?

Debating whether or not to designate this one as donor unit. Looks like it might have gone for a swim sometime during it's life.

Oh, it's an SP first series, I believe.

Any thoughts or guidance welcomed.

Thanks

Fiddler

There are several styles of cross tip.

JIS, Japanese Industrial Screwdrivers are essential with any product in the last twenty years from Asia

Hozan JIS-5 JIS Screwdriver Set (NEW 3rd Gen.) - - Amazon.com

Take another look. The kit I bought did not include the long driver.

The 1 driver and the 2 driver have the same size handle and the same length. I used a file to carve two grooves at the end of the handle.

Thanks. It's a 1.34mm threaded shaft that's left behind in the Camera.

Didn't realise that broken screw extractors came that small, but, I've only been playing this "game" for a couple of weeks.

Cheers

Try using a sewing needle to try to turn the broken stump of the screw. If the thread is not locked or bottomed out, it may start to turn until you can get tweezers on it.

That's a good idea, thank you.

Success !

Thanks to all. Good to have suggestions from others, helps remove the blinkers.

Finally, with Needle and eventually Tweezers, the little Darling came out.

Thank you Pentasonic49, excellent suggestion.

Excellent! I'm writing that technique in my repair notebook.
