I've disassembled, cleaned and regreased several pairs of run-of-the-mill Japanese porro prism binoculars without much problem. Now I have an old pair of Hensoldt roof prism binos with a very stiff focus mechanism and I want to give them the same treatment, but I'm not sure about the differences in the design of the focuser. I don't want to start unscrewing or removing things based on my knowledge of porros, and end up messing up the roofs. Can anyone share some tips based on their experience?

I take plenty pictures as the procedure progresses - they're easy to delete. I also take light cardboard and label where each screw came from and put it in a hole in the cardboard. Make notes of your disassembly, sometimes how to put it back together is not as straightforward as we hope. A complete guide is in my signature.

Hi

 

Specific to roof prisms : don't hurt the roof edge.
