> First - the key was soldered with regular low temp solder, and it failed. Second, the low temp solder must have gotten into the tube and attached the tube to the screw.
So - the screw cannot be removed.
I have re-soldered the key to the tube - again using low temp solder for teh time being... but I cant get the screw out, even if I completely desolder the key.
-----------------------
Hard to say w/o looking but it is not necessarily a solder, it could be rust holding it. If it is solder you should be able to heat it and then twist it out.
If rust, try something like rust buster, it could help. If it doesn't try the combination of rustbuster and heating. If it fails you can always buy a top joint on flee-bay for 10$ and use posts/keys/screws/rods to do repairs. Cut posts open, drill screws out, etc. Options you list would work; just pick one which would be less hustle.
If you are using regular soldering gun, use silver (lead-free) tin alloy; found in plumbing supply. Do not confuse with antimony alloy, it should have sterling sign. Ag/Sn is x2-2.5 stronger then lead/ and antimony/tin alloys and doesn't turn dark. I had soldered keys with it and they held.
I have an Evette with K1357 (yeah, 20 numbers apart) which needs to be repadded, and I am not looking forward to. It is playable now, but ~50% screws froze, it would be tough to get out.
BTW K-series was made in Paris at Buffet factory somewhere ~1946(?) by Buffet trainees. It plays nice, but the wood is sub-par (WWII supply shortage). Some tuning issues, 12th are wide, need to shorten joint.
