The new, correctly-ground cam followers arrived from Keith at Calver Special Tuning. Unsurprisingly, they’re exactly right at c.75″, and all absolutely identical.
I photographed each one as I measured it, but they’re all the same so there’s hardly any point in posting the pictures.
Just a reminder: the old followers (with 500km of use) measured all over the place. When Minispares sends me a new set* I’ll measure them and see how they compare.
*Since the old ones are clearly defective, I’m confident that Minispares will send me a replacement set. Yeah right.
