Maybe I just didn't heat it hot enough....it wasn't glowing red - just good old burn yourself hot.
NOTHING wants to be glowing. Aluminium doesn't glow, it get does get a bit shinier weld it is molten but you don't want you gearbox housing ending up as a puddle on your garage floor. Alumium while having a lower melting point is a great conductor of heat so it might take a bit of heating as it sucks the heat away pretty quickly. Heat it until it is just a bit too hot to touch. There is no point whatsoever in heating the plug. When it's hot start giving it the treatment as stirlingmac described.
Also I see the plug it still quite square- if you gave it a really hard time I would have expected you to have rounded it by now?
