To be honest GW I can't remember as I haven't had the need for quite a while and its a pain to fit as the tolerance on my spindle is quite tight to put on and get off... always worried about chipping blades... so I'm not gonna rush off and fit and try at the moment.
However, having said that, by the fact that I cant remember makes me think it has not been an issue as I can remember the batwings with some of my blades with my spline jigs.
If your first cut is too short... Take the second cut from the longer end... LBD
