TheTigerUK said:Some times it can also help if you tighten it a shade more before you try to undo it.
Then there is the hot and cold treatment which can help as well.
Then there is the curse and curse even more method just before you are tempted to hit it very hard with a hammer !! seriously i have had some that tight i think a steam press had been used on them.
I asked you not to give away my secrets. Took me 11 years in the Navy to develop the vocabulary necessary to repair watches.
Try cooling the caseback with an ice cube to contract it slightly. Takes a little while but has worked for me.JoepeteJokla said:I have a really tight caseback that will not loosen. I have a caceback opener and a very small vise. Any advice on how to open the caseback is much appreciated ...
Kevin,kmcnyc said:I have an LG wrench and a crap vise... the aluminum one with the nylon dies that costs like 3$.
usually the LG can open anything.
sometimes its about using the right inserts or blades or what ever you call those little dinguses, that insert into the wrench.
and yes tiny taps with hammer do help awaken old threads.
If that does not work I go to my watchmaker, and the parts guys very conveniently next door ,
(84 and 88 bowery for you folks in the city pardon my shameless plug)
with my tail between my legs and ask the guys to borrow the "real' vise. Or 'real' tool they have a bergeron big thing with a wheel on it that costs like 2 grand or something crazy.
Usually they are happy to help- but I do buy most if not all of my crap there, yes its overpriced but when its time for stuff like this, or to 'borrow' the pin vise, or the staking set, or the begeron bezel tool..
and its always a mixture of disgust and fascination that they 'loan' me these things in their store.
to watch me use something wrong, then they sigh and help out.
