Remove top 2mm of metal from the head

First make sure the blade assembly is removed from the Thermomix.
Next file (or angle grind) away approximately 2mm of metal from the top of the blade shaft head (the metal to be removed is highlighted in red in this picture).
You want to remove enough metal so that that the 6mm shaft is visible from the top of the head..
