Any good machine shop can make a jig. Give them a drum, or rotor, and have them make the jig bolt to the current bolt pattern. Then tell them the hole size, and the dia. circle, and number of holes. The mill I have here at work has a DRO(digital read out) that has a program on it that figures the hole spacing by just giving it the circle dia. and hole size, and number of holes
. I know this doesn't help you, but it gives you an idea to find someone across the pond to do it... even if their mill doesn't have DRO.
