Thanks for your suggestion.
I'm surprised to receive so few answers to a problem that seemed very
trivial to me...
You can get dozens of answers for a patent problem but only one to a
daily problem that every ham has encountered at least once in his life

Practical problems have practical solutions - you got the most common
one that works. Same advice works for getting aluminum wheels off
brake hubs. That's pretty common too. Or get a bigger hammer.

If you want more correspondence, ask for a patented method - and then
try sifting the details from the obscure responses. There may even be
a method employing the weak force generated by the crippled Large
Hadron Accelerator. The corriolus force (twisting) might work too.
