Ah right, I put the guard in, marked it up and with a fresh Stanley knife carved out an arc on either side - little by little I kept placing the guard back between the fork and stopped when it just sat nicely without being squeezed. I then finished off the arcs with a fine file. Because the arcs are only the width of the fork blades you can't really see, I think I would struggle to photograph it without removing the guard.
