So the issue is removing the reverse-thread two-hole screw in the middle of the Krasnogorsk-3 winder. I am reasonably skilled in the camera dissembling department, but cannot fathom how to unscrew this piece without ruining the entire component. There have been words on these forums about a "special tool" that can slot into these two holes and work off the screw, but I have been unable to source a specific product or method to remove said screw.
The screw is on there very tight, and I have tried the "two small screwdrivers" in each hole to no joy. And it seems a crying shame to ruin an otherwise decent piece of chrome.
I can't imagine changing the spring of a broken K-3 to be too rare an occurrence, so if anyone could tell me how to unscrew this little bastard, I would be very grateful.
Many thanks 🙏
