Tony, you mention using some stud lock. I assume Loctite is the same thing or at least does the same job?
Thanks
Locktite comes in various "grades", for dumb folk like me they are colour coded - Blue for stuff you want to undo again without heat and incantation, Red for stuff you might want to undo one day and are prepared to have a heat gun at to help it along and Green for stuff you do not ever plan of moving again - I've forgotten the number designation for Green (blue is 242) but at one time it was marketed as "super stud lock".
It works. At home I have a very valuable, hand made wind-up watch I inherited form a great grandfather, it has its "chronometer" certificate engraved on the back. One day when winding it the bezel came loose.
Quick as a flash I knew what to do - a drop of "super stud lock" would fix it. Pity about the 'wick-in" properties of the dammable stuff.
Some years back the manufacturer gave an indicative quote of EUR1,000 carefully take it apart, clean it up and get it working again, they kindly included fixing the loose bezel in that. I really must get it fixed whilst there are still watchmakers alive to do the job.
