Geography geography geography! Don’t it create problems , especially with the North Sea in the way. If you were local, 75mile radius, you could have popped around & borrowed my taps & dies, in fact you could have taken mine & I’d make some more, assuming there was some advantage in fitting them.
I’ve have some reasonable schrader valves also & fittings to weld into spheres, again that was a job for my spare spheres but I’m now to old to be arsed.
The offer stands if you want a week or so in the UK.
