DYI lens polishing? Anyone?

The end!

The end!

Hi folks!

I ended my polish experiment yesterday.

I´m quite happy with the results.

the "girl gone crazy" pic is before and the "i´m going to kill you slowly" girl is after.

The lens is still flary but not as before and resolution is almost the same.

I should have done a more cientific test.

The method was using a small wooden tip (1 sq. mm) and brasso, silvo and some polishing paste for car paint.
I made small circular movements, perhaps 6 continous hours.
I couldn´t make a cast of the lens since i couldnñt take it off it´s brass housing.

Now i can use the lens, i´m very happy about it.

Of course this is a 10mm diam lens, so it´s "easy".
I´ve seen fast glass professionally polished that developed scary spherical aberrations!!!

The method of dismantling the elmar is taking off a circular press black cap that hides a master nut, this has a tiny screw. you take it off then unscrew the master nut and voilà the lens is yours.

The elmar is a gem i had one years ago and was really great, so if you can get one donñt hesitate it will deliver fine images.

So i must say this method will eventually do for relly kaputt glass.

Regards!

Do happen to have any pictures of steps of dismantling ? I have one that feels like there's a loose element and never is really in focus, It's in very rough shape all around and more of a body cap at this stage.
 
Thank you johannielscom

Andrew, i don´t have pictures, have you experience dismantling lenses?

on the back side ther is a black rim that has an outer diam of 27mm adn inside diam of 20mm...you must pluck it, since is a press cap...then you will have in sight the master nut, it has a tiny screw to secure it...you must unscrew this little thing then unscrew the master cap.
Once done this you´ll have complete control of the lens.

Regards
 
Thanks, I cleaned haze out of a few other 50's before but have no idea what to expected with this one, if might be something that needs to be tightened or could have internal damage. As it is now I can't really make it any worse.
