Re: Taking bases off valves, safely?
I've found that if you can find a convenient jar into which the octal fits and can be filled with enough meths to easily cover the base, if you leave them overnight and then try going round with a hot iron and tweaking, the valve comes off easily. The shellac and woodflour cement is reduced to soft sludge.
If the jar has a screw top it will do for many more candidates.
If you only want the base, this is still the best way to go because you can clean out the cement with a bit of bogroll and have a clean base.
If you decide to go the hammer route, be sure to wear full protective clothiing, but you''re still likely to have the cement to deal with as well as the hazards of broken glass.
