Hi all, despite being a long time reader, I am a new member to the forum. I have been slowly restoring my IIIa, which initially needed the slow speed escapement cleaned, and the RF mirror replaced. Last week I finally had the whole thing complete, re-covered, test roll shot, everything was perfect. So after a few days of it sitting in front of me, and periodically picking it up to check that what i had done a good job, the RF just changed its mind. It did not fall, and was not in the sun. What seems to be happening is that its infinity is now at about 1m, and its closest focusing point is at about 30cm. Since I never touched the RF mechanisms, i am pretty sure that the cam has not moved, and it still has a full range of movement, it is just not focusing at the right distances. Does anyone have any idea what could have spontaneously happened, or how to rectify this issue? Also, on a side note, due to the time that passed between my starting the repair and completing it, i have forgotten what held the end caps on the RF tube: were they cemented in, originally? Thanks for your input, Tobias |
