Has Steven Tribe wrote that he has done recementing? For himself only I think.
Coatings are another matter.
I just had my secondary cataracts lasered, of course it was expensive, but maybe somebody is working on old lenses with laser.

I think that there are a number who do "own" recementing and can sometimes be convinced to help others.
I still do it quite regularly, but will no longer do it for others as there is a quite large risk.
Strangely, the process (demounting glass, delamination and reglueing) never seems to fail. The problem I have encountered is devitrification of the top outside surface of the achromatic lens used in Petzvals. It so happens this has only occured with English crown glass from Chance Bros. But this includes an awful lot of interesting ( and valuable ) lenses. I have had an expensive glass failure with a Dallmeyer Patent Petzval where devitrification spread down from the top surface in a matter of minutes. This was inspite of using exactly the same procedure as for dozens of previous attempts!
John at focal point would use heat to separate the elements and sometimes they would haze up. The last time he did a lens for me, the glass became hazy during the process and he thought it was was ruined. However he was able to clear it up with a light polishing. After he was done he told me that it would be the last cemeneted pair that he would work with. This was a Hermagis Eidoscope.
I'm guessing that polishing cannot be done at home?
Has anyone had experience with Kanto Camera?
Threads merged.
I wonder whether some lens manufacturers offer the service.
Hi everyone, my first post so I hope it helps.
I was watching a lens on a popular auction site and the seller said he had his lens cla'd by this chap in the UK.
"Graham Rose Enterprise Services". I researched the chap and he states in his website that he polishes and recoats optics, mainly for the movie industry. I've no idea of costs involved and I have no connection with him.
I came-up with this, with a DuckDuckGo search, and they're in London.

Good to know!
It must be possible outside of a Lens Factory.
Burke and James Chicago had a huge operation for polish. coating and remount.
I never saw the operation, but reading the historical catalog is impressive. They rented nearly any lens.
Even rare goodies.
