The period of a pendulum depends on the local value of g, so it won't work in deep space, free fall or orbit, where g = 0.I think you need to take this onboard...
But yes - a pendulum would not work in free fall, or orbital free fall. A pendulum that is in deep space, but not in freefall, will hypothetically swing very slowly indeed to the tune of the nearest g-field.
(Btw Alan - I was lucky enough to catch a glimpse of the Red Arrows flying by in formation today. Wonderful sight indeed! Made me think of you...)
