Help: 40mm Nokton Re lube

[rlouzan]

Hi,

I´m having problems removing the screws😱 that hold the focus scale, and inner helix on my 40mm Nokton. I´ve used Hydroxen Peroxide, Penetrating oil, Ethanol, acetone + heat from a 30W soldering iron on them, but the screwlocking compound won´t budge.:bang:
What am I doing wrong?

Thanks,
RLouzán
