Is it at all possible to get replacement flanges for older Nikon AF lenses that still have the worm drive (AF rather than AF-s)? I picked up a job lot of lenses that includes a 28-100mm G in nice condition except that the flanges are mostly broken - there's a small bit of one and a really tiny bit of another, the rest are gone. It still works if you hold it in place so I'd really like to get it fixed.

 

The problem is that all of the replacement flanges on offer on eBay are for AF-s lenses - they don't have the hole for the worm drive and presumably there are other differences. I'm very tempted to try to make the flanges from epoxy glue, but I'd really hate to rely on that sort of bodge holding together forever.

 

Anyone know if there's a way to get hold of them - do Nikon still do spares for lenses that old?

Hello Marcus

 

I have an example of your lens I bough cheaply on Ebay recently, & was intrigued by your inquiry. Looking at the mount / flange you mention, I can see why they would get damaged – all plastic and not built to last.

 

I found lots of Nikon manuals & parts lists at learncamerarepair.com but not your lens. The site owners do suggest they have parts available. Wonder if its worth making contact with them?

 

Regards

Pete

I've used their contact form (and written N/A in the compulsory phone number space because they really don't need my number for this), we'll see what happens. I also emailed Nikon UK on Saturday, no reply so far - not surprising given the bank holiday weekend - but we'll see what happens.

No luck with either, unfortunately, Nikon seem to be about as much use as a chocolate teapot these days, and learncamerarepair suggested I try repair companies, which really isn't a lot of help given lockdown. I think epoxy resin will unfortunately have to be tried.

That's an unwelcome outcome Marcus.
Pity we don't have a forum member with a 3D printer.

I know someone who has one but the quality isn't good enough in my opinion. There's a couple of places I want to try, but if I have no luck I'll try the epoxy resin thing.

Epoxy resin worked quite well. I could have got black resin but it's advertised as being suitable for repairing metal rather than plastics, and may possibly be conductive which is not ideal given the electrical contacts on the lens. In the end I went for a strong normal epoxy - the one I got turns out to dry white, which looks a bit odd, but doesn't affect operation. Now trying to sell it, we'll see what happens.

I think you've done well with that.

The sample pictures along with the ad look pretty convincing.

I could have probably got it a little smoother but I didn't want to risk messing about more than I had to to get something that worked.

I forgot to say that this sold for a fairly good price and the buyer was happy with it, so far as I know it's still OK so this is a viable repair method.
