Titanium HRC valve retainers

Its been a titanium valve retaining week this week, i started off making 24 for a Westlake (3 Westlakes to be precise) and rounded off with 8 copies of HRC ones for an SP2, these in fact.

The HRC retainers are stepped inside so i had to get a stepped cutter ground up to the right angles, even so cutting the taper its not an easy thing to do in titanium, all it wants to do is rip the cutter to bits, so its slow and careful work with lots of puckering!
