3-spline lock ring removal from 1980's Miche headset

Postby robjordan » 27 Jan 2016, 11:25am

Hi there - I'm trying to disassemble a 1980s Mercian for refurb and encountered this 3-spline lockring on the Miche headset. Anyone know where I could get a suitable tool to remove it?

If a standard lockring removal tool, of the sort that you'd use for a traditional bottom bracket, or fixed gear sprocket lock ring doesn't work, I'd suggest using a hammer and flat headed punch. The lock ring should not be under a great deal of torque, and this should get it moving without any damage.
