Thanks for the alum tip, that solves the main problem thank you.I'm guessing you're looking at a pin pallet escapement...pictures would help. I seem to recall some discussion in the past 6 months about this. From memory, not seeing what you're seeing, you will need to use a solution of alum to dissolve the steel pin in the brass anchor. The past discussion was then using sewing needles for pin replacements.

This whole anchor is very small. Is there a way to stop the arbor getting corrupted with alum-maybe lacquer?Thanks for the alum tip, that solves the main problem thank you.
BrassIs it a brass or steel anchor? If it’s steel you can’t use alum because it will dissolve the anchor.
Its chemical name is potassium aluminium sulphate and you can certainly buy it at food stores, it's used in some pickling processes.What is Alum solution.

To use it for removing steel parts from non-ferrous metals it works best if the solution is saturated and warmed; warming it allows more to dissolve and it speeds up the process. You must be absolutely sure that there are no other steel parts in contact with it that you want to keep intact. The steel will turn black and bubbles of gas will be released.
