I worked on a Pax M3 with a frozen focus, and found that 99% isopropanol alcohol was the best for freeing up the focus helical threads. The grease was some kind of green hardened deposit and was resistant to naptha (Ronsonol) which usually works. I soaked the whole thing submerged in the alcohol for a few days before if freed up enough to unscrew. Another problem I had is that the wind lever appeared cracked, then fell apart as I was removing it. It looks to be a cast pot-metal bit, and was just too fragile. I intend to file one up from aluminum plate, perhaps I can instead persuade Winfried to do this...? |
