Recently i bought myself a beautiful Dallmeyer 3a!
It's in beautiful original shape.
But there was one problem. All the lens elements were stuck
Also the soft focus function.

As i have tried this solution before on a Hermagis with a severe stuck rear element i gave it a try again, but now with this beauty.

All you need is a fitting piece of thin rubber, a screwdriver, a LITTLE hammer and a large hose clamp.
Cut the rubber just as wide as the clamp itself. Make sure you cut it a little shorter to keep the place open where the screw is.
This to make sure you get an equal pressure around the element.
Tighten the hose clamp slightly. There is no need to tighten it hard! When you tighten it to hard you might break the glass!!!
After that you take a small hammer and gently tap on the screw in the direction the element has to go loose.

Before this solution i have tried several options. I tried silicon spray several times over a few days, tried to unscrew it while wearing special rubber gloves.
Nothing worked. Now it came loose within 2 seconds.

I just wanted to share this with you.

Before resorting to that much pressure you could try using one those nylon ratchet fasteners. I use one about 3/8" wide to open recalcitrant paint tubes. Just wrap it around the cap, serrations inside, grip it firmly as near the cap as poss & twist - always works. Dennis
PS Also works for stuck filters.

If that rock hammer is a standard size that lens front element must be HUGE!
