1 or 2 people were swearing by that JB weld for attaching new dial feet at one point on the forum, but when I tried it i found it was only a shade less than completely useless, I don't know if I'm doing something wrong but I've never been able to get any kind of cement to bond properly between the replacement copper dial feet i have and the dial, always snaps off without barely any effort.
I think short of special, costly welding equipment you have to accept that dial dots/strips are your best shot, it's the kind of thing that irks most repairers, we all want a better way of doing it i think, but it usually works out okay, at least if the movement ring is a fairly tight fit in the case.
