That is around 60-70°C, depending on how thick-skinned your fingertips are. I've always wondered if that really helps. It isn't hot enough to temper steel. Is it only to allay our fears of breaking of the pivot? And if the pivot breaks, we can console ourselves that we had tried our best. I normally put my soldering iron tip, set to 250°C, at the point where I wish to bend the pivot and heat it for about 30 seconds. Does that work? Honestly, I don't know. But at least that is at tempering temperature range. Have I broken any pivots trying to straighten them? Sure! But at least I've tried my best. 😅 -

I straighten pivots like this routinely. Get the part running true in the lathe, not counting the pivot. Heat brass or nickel tweezers in alcohol lamp until you can barely hold them, and use them to coax into alignment. -
Well I just found out that 90% of the designs I like have the numbers painted with radium paint, so I think that's ebay fever cured 😆 -

Thank you ColdWind, I did try the alum solution and albeit slow (I am on my third bath of 6 hours at 70° C with a solution of 10ml of water and 2.5g of alum) it seems to be working. I can now screw in the new stem, at least a few turns. I expect that at some point I will be able to screw the stem in all the way. Perhaps next I will try a bigger bath. I wonder if the limited amount of alum is slowing down the process? An happy side effect of the alum bath is that it removed the oxidation from the crown!! claudio -
This will take some time. I need to do some reading and watch a video or two…Thank you for all the detailed help @nevenbekriev
