Good luck PJS - hope you have better luck than the rest of us.
I just got my welded rim back from the engineering company. Because it is on the inside edge of the rim it will never be seen thankfully.
Fitted it and all seems good - for the timebeing. They reckon that it will crack again somewhere else though.
