Mr T - Apologies for my poor choice of words.
What I meant to say was does the arc of the bonnet closing require a slightly larger hole to slip over the pin?
Cheers, Paul.
PS
I did think of you earlier as I was filling/sanding my own bonnet.
It certainly makes me appreciate how much effort you have put in to get such a smooth result.
Whereas my bonnet looks like the surface of the moon.
