Thank you for your nice post. There will be a lot of water in the Vistula before I get enough practice... . Besides, I suspect that not every repair will be successful. You have to take into account that there may be a leak in the anode lead (I've seen such cases) or the glass may break due to stress. I advise everyone not to throw away damaged picture tubes as long as the screen cone with the piece of neck is intact. There may still be a chance for such CRTs. Let's save old picture tubes!
Currently I am working on the topic of phosphor P4 (white). Perhaps I will try to make it myself. Below are some test photos of the various phosphors I have.

I fully agree and I'm also going to forward this thread to the Austrian collectors community. Of course I cannot promise anything but the more interested people know about you and your ambitions, the bigger the chances are being successful and save old CRTs

I'm currently building a machine to fuse electron guns and lengthen necks. The machine will work vertically. I'm a bad mechanic, so this work takes a long time.

It looks like a nicely made machine. I'd probably make a ring for those 4 posts the cone of the tube rests on to support and restrain the tube better. I don't know if you will ever encounter some of the tubes we have here in the USA, but I'd consider making the loop capable of holding a 27" CRT and I'd make the neck hole capable of handling 2x the standard monochrome neck diameter to handle pre-1965 color tubes and electrostatic deflection tubes like the 7JP4 and it's scope tube cousins.
