There's always a risk associated with using the lens vise. I was mostly successful with the tool, with only an occasional failure. For instance, on a rather badly bent Minolta MC Rokkor PF 58/1.4, the filter thread was kind enough to get back to close to its original shape, allowing me to screw filters on and off without issues. BTW, I used your video on that lens as a reference to also repair the stuck aperture. However, on an Olympus M.Zuiko 50/1.8 with a really nasty thread deformation, it was impossible to get it straight and the branding ring indeed got damaged during removal. In general, the heavier the deformation, the more difficult it is to straighten it with a lens vise.
@@FocalReduced Replaceable threaded tips with different diameters would rock, wouldn't they? Still, I think the vise's large side is like 46 or 49 mm. I've failed to fully repair a 49 mm thread (the Oly), but I've had success with a 55 mm thread (Minolta). Just a few minutes ago, I successfully repaired a 52 thread on a Helios-44M. I believe there's more to it than just the filter diameter.
First of all thank you for interesting videos, especially for radiation testing. For this repair you need one more step on my opinion. Get the thread file from video(right step size) and little by little "clean" the threads.I hope that will help you to unscrew the nameplate because you already made it round enough. Thanks to @JaneRanta for video.

Yes. Unfortunately, the tool is not optimized for specific filter diameters, so it may work for some, but not all.

We will definitely need to try again on another lens.
Have you tried this technique from Tested channel ruclips.net/video/jMyUi_umDZg/видео.html ? Also, did that heat in the start actually do anything?
Thank you for the link.

Thank you We will give it a try on the next lens we receive.
Damn this is disappointing. I have this exact lens that I was going to buy this tool for.
