I have got to have a bit turned out the centers of the fronts of these so they fit the adaptors again as to had 1.5mm taken off the back face to try and get them to fit without rubbing.After a remeasure i could see i wasn't going to get enough off so got the dog with them and they are still sat next to my mates mill.If i was to find a nice set of normal splits this may help get me motivated to get them done.
