How to re-secure hairspring stud, Poljot 3133

[mikepilk]

Puttiing the balance back in my Poljot 3133 I discovered that the hairspring stud isn't securely fixed - the angle of the hairspring at the stud can too easily be changed. 

The pic isn't very clear, but it seems to be some sort of plastic holding the end in a slot. 

What's the best fix - try to scrape it out and use glue (epoxy?)

If all fails, new balances are available. 

It was all going so well until I discovered this

I assume by plastic it's probably glue?

I know that the Elgin watch company for instance was using the glue. But they don't actually say what the glue is and in the book is just now looking at they comment it was not available to the watchmaker because it required special equipment? If you're interested I could scan the pages in they talk about using shellac but that's also because this was written in 1958 and I don't know how much epoxy existed back then?

I would fall Elgin's advice of cleaning out the old blue and I would probably use epoxy.

@Nucejoe gave a pretty detailed step-by-step in this thread

for re-securing the hs with epoxy. I'm planning to give it a shot.

It breaks up like a plastic, not like any glue I know. Possibly from a heated glue gun ?

As shown in the pic, the end of the spring only goes about half way across - not ideal !
