Does the length give it more torque having a 9ft pendelum..?With the tower clock sitting on the floor through which you plan on cutting the hole, the amplitude of the pendulum shaft at the floor level will be a lot less than the amplitude of the pendulum at the bottom end. I think you won't be needing a foot. Hopefully the opening will be small enough that the family chihuahua won't fall through!
I have finally bought the clock with the 9ft pendelum.. It is a E Howard No2 with 4 50 inch dials and complete drive train..A clock with a seconds beat pendulum (60 bpm) requires a pendulum approximately one meter long. A clock with a 40 bpm pendulum requires a pendulum 9 feet long (or approx 2.78 meters by my calculation). To try to produce a tower clock of any size that would have a 60 bpm pendulum would require some peculiar gear train configurations for a tower clock (IMHO). I still contend that a 2.78 meter (9 foot long) pendulum is proportional in length on a timekeeper the size of a tower clock when compared to a one meter pendulum as compared to a timekeeper the size of a tall clock movement. Smaller tower clock movements would reasonably use a shorter pendulum with quicker beat. Consider the more rapid bpm rate of a post (or street) clock, for example. The movements in these quite resemble a tower clock but are much smaller.
