Small screw loose

So I've had a screw come loose...

More specifically the screw at the bottom of my Ikonta that holds a bar involved in the film transport, it was corroded and disintegrated. Any ideas where I could source another? It's pretty tiny.

Get in touch with Miles maybe, or try a local watch repairer.
 
 
A jeweller who does repairs, not necessarily a specialist watch repairer?
 
If you're a specs wearer, see if any of the screws in any of your specs fit - if they do, use that screw in the camera and get the supplying optician to replace the one in your specs. Just take care and make sure the screw is the right thread - they're so small and fine pitched that they're very easy to get the wrong thread in there and/or strip the thread.

Try a local Model Engineering Society, they're usually really helpful guys and have an interest in all things mechanical. Easiest route may be to have it tapped out to a fractionally larger, more common thread form.

Struck me we ALL missed the obvious here!:D:D:D

Did you ever get sorted with this Steveo?

I have a few tiny screws that I obtained after dismantling an old broken zenit…..perhaps one will work for you;)

I completely forgot! I've got too many cameras (according to the wife) but actually I've got a broken Zenit somewhere now you mention it.
 
Is there enough left of the screw to determine it's size & thread?
I've bookmarked an assortment of tiny metric screws on e-bay.

But haven't actually ordered any yet despite them being under £4. There seem to be quite a few alternative suppliers.

Even if the original screw wasn't metric it should be possible to re-tap the hole - probably easier than finding out exactly which thread it was!

Edit:
I've just remembered I've got a screw missing (to balmy just to be described as having a screw missing?) so I have now ordered a set.

I've got another still in the camera I could measure but tbh I'm not sure where to start

Just ask a local engineering company to check it with a pitch gauge, takes about 30 sec!

If you have vernier calipers or a micrometer you can measure the diameter & length. This diameter will be only fractionally less than the quoted size (round up to the next 0.1mm?)
Thread pitch can often be identified by using a known thread (such as a filter) as a pitch gauge. As @gcgraphs mentioned it only takes a few seconds, much quicker than finding an engineering works round here who have small enough pitch gauges. The engineering dept at work are more used to 20mm diameter bolts than 1or 2mm ones, even our instruments dept don't normally go small enough for lenses IIRC 3mm was their smallest last time I went on the scrounge. :).
 
Finally.... I've been biting my nails to the quick waiting for a resolution to this problem :)
 
That's the thing about film photography - it slows the process down a bit!
 
I'm courious why it's corroded in the first place? In my experience screws often come loose (I'm missing a few so my friends say) but corroded is a bit more worrying, what else is affected and whats caused it, battery leaking maybe? I'm thinking that camera doesnt have one but I'm not sure.

It maybe got a bit damp in the past. No electronics to worry about and the shutter mechanism works at all speeds so I suspect it's just old age
