[Dixielandjazz] Re: Cryogenic treatment for brass

[Bill Haesler]

Dear Bob,
You said [snip]
> It would be impracticable to stress-relieve musical instruments because the
temperature involved would damage non-metallic parts including the lacquer.<

Which reminded me of a mate who decided to save money and re-sweat the spit
valve back onto his cornet.
The resultant heat melted all the tubing joints and he finished up with a
very collapsed instrument.
It cost him heaps to have a professional rectify the mess.
Kind regards,
Bill.
