Ariel 7075 alloy valve spring seats and caps

Valve spring caps are always a good one to do in 7075 alloy as its strong enough and light. But they are very fiddly and tricky to make as accuracy is all important. I get cutters ground to the right angle (14 degrees) to form the taper for the colletts, but even so they take a lot of concentration and careful machining. The seats were a bit more straight forward but have an undercut in the bottom so again needed care in setting up to ensure concentricity.
