Hi Murks. Just asking if you are aware that most crown wheel screws  have a left handed thread. Sometimes indicated by a line either side of the screw slot, not allways but when that indication is there you know it is definitely left handed. So that screw can occasionally get broken off or the thread stripped, i will assume this is what has happened hear. Post  close up photos of the screw and the threaded hole it fastens to.

We cant tell from this photo murks. You'll need to get in close with a x20 loupe to fully inspect the screw and hole threads. If you are lucky the majority of the thread loss maybe on the screw and a new screw may provide enough grip to continue with your build. This is all providing that this is the original correct size screw. In watch repair always keep in mind that parts may not be original and may have been incorrectly used.

Is this the same Lip R25 that are working on?

In your other post, the cap jewels for the pallet fork and escape wheel are also missing. Looks like it might be more viable to get a donor movement than to attempt rebushing, rethreading and replacing the missing jewels.

      This is a very valid point and a subtlety that I was unaware of until fairly recently, learning all the time, the video below explains this point well:

      You don't have to use his special tester. Any good multimeter would work.

      Yes, it looks like GT Revue 30. Doctor, You can not replace escape wheel by the dimensions You listed. One needs to know much more things like number of leaves of the pinion and it's diameter, the position in high of the table and the pinion, the hight between the pivots, the exact pivots diameter... And then, even if suitable wheel is found, one will need to know how to adjust the pallets position correctly. Restoring antique movements is something different than replacing parts. In older movements parts are not interchangeable, this means spare parts do not exist. Here the case is different, but still escapement adjustment will be needed if a wheel from a donor is found. So may be it will be easier to restore the donor for You...Restoring antique movements usually means making of the parts needed and this requires knowlage and working on lathes skill. In this case repivoting of the wheel is the natural solution, but there is a long way that one must walk untill getting ready for such work.

      How to store one dip

      I was looking at Essence of Renata, a chemical used a lot for cleaning hairsprings: "Specially prepared solution for degreasing watch and instrument components. Indispensable for degreasing hairsprings." Looking at the MSDS you can see this is just pure n-Heptane, so could be an option for those who don't want to use the chlorocarbons or hexane?     HF6013 - Horological Essence COSHH Safety Data Sheet Horological Essence_0.pdf
