·You can dissolve it out using alum powder.

·That’s a thing?
Do I just throw the whole crown in the solution? Or drop it carefully onto the stem ?
What about rubber gaskets or the plating?

·Carefully remove the tube far enough to get precision pliers on the stem. A dremel can be used if you have no machinists tools. Remove the tube but not the stem. Pretty simple. 2 or 3 mm off the tube.

·I would recommend against the chemical method. I wonder what Archer would do.

··Melbourne AustraliaIt looks like you have enough protruding stem to use a slot file to make a screwdriver slot and unscrew it.
If the stem is steel I think he would use alum solution, if it's stainless he may use the file. Just guessing though.

·Betcha that stem was Crazy Glued into that stem. In my view, alum is the way to go. It shouldn’t affect the washer that retains the internal gasket (stainless steel?), the gasket, or the gold finish on the crown

·I use a small jewelers burr to carefully put a smaller hole in, then use a size up jewelers burr to bite into the hole you just made and then gently unscrew it, I would heat the stem with a plasma lighter first too, to hopefully soften any thread locker without having to heat the entire crown as much.
A Japanese watchmaker I met showed me this method, I will try and find the video he put on instagram of the process.

If that fails - alum.

·The photo makes it look like the stem is sticking out further then it actually is.
I’ve got some alum so I’ll drop it in and see what happens lol
Thanks everyone for your advice and suggestions

·My anti alum bias comes mostly from having never owned or used it for anything. Ignorance on my part.

·I've used alum successfully on 5 or 6 crowns recently. It takes time, perseverance and for me anyway repeated attempts, but it worked and that was the main thing.
