I did a search for something similar here but I wasn't able to find any threads related to this.
Let's just say I'd like to unscrew front and rear lend element from Verito (in Wollensak studio shutter) and both are stuck. Moderate force accomplished nothing. I would like to do it by myself and I'm not seeking any professional help like SK Grimmes or any other shop.
Do any of you know the tips or tricks how to do it?
