Small centre drill to start with, then use a 3mm drill to drill in the centre. Then finally use and easy out (screw extractor). I just done 1 on my SP1 a couple of weeks ago. The guy before me had just glued the head of the screw back on after he had sheared it
Managed to get it out, welded an Allen key onto it and slowly worked it out of the half ton of thread lock that I got carried away with. Had to be careful as I've only just has the wheels powdered! Clolin i was also tempted to super glue it back and ignore it.
Glad to see hear you got the bugger out Also nice to see another black n white blade With white wheels
I know what I like and it's black and white,black and white and a bit more black and white! It's the way foward !
