Aye, so it'll be *pictures* you'll be wanting now, is it? Begorrah... Well, this started as a cry for help, not as a tutorial, and it's become more of a (lack of) progress report. But sure, I can provide some pictures, although I shot all these just now, not as the work progressed. So some are re-creations, especially those of the Petri mount before being totally dismembered.
First, the lens topside. Then, a recreation of the original mount. (That goo inside is the Gorilla Glue I didn't scrape off, inked to hide the mess.) Then, a comparison of Petri mount (base cap with lip, and bayonet ring) and the M42-PK adaptor. Then, the adapter sitting on the chopped base cap, which was all too thick. Last, the adapter sitting on the body base, where I'll superglue it tomorrow.
What I've learned from
this exercise is that a Petri lens can be converted to PK rather simply. A small Phillips screwdriver to remove two screws, and a Dremel blade to cut away the third bayonet retaining pin. A cheap M42-PK adapter, and SuperGlue to attach it. At least, I *hope* the SuperGlue will work. That's all.
