Karst - I looked through my notes but a lot of the stuff I had when I was working on my own console (never finished it so don't expect pictures, gang) has gone the way of all organic matter. I do recall a lot of what I had planned to make the time rotor go and spcglider has it right. Think of the way the old steam engine wheels work on trains...but apply it in reverse. Instead of the piston driving the wheel have the wheel drive the piston.

You'll want a variable speed AC motor and a gear to attach to it with about a one foot diameter. I think it's one foot, it's been years since I've thought about this. Mount the motor beneath the timer rotor but high enough off the floor to allow the gear to turn unhindered. Attach a rod to the gear on a bearing joint and the other end to a joint at the center bottom of the time rotor assembly. The motor turns the gear, the gear spends half it's swing driving the rod (and therefore the time rotor) up and the other half bringing it down.
If the motor has trouble pushing the time rotor up you can set up eye hooks high near the apeture the time rotor comes through and a second set of eyes at the base of the rotor and then tie weights onto strings so that they help pull the thing upward as the motor pushes it.
If any of this fails to make perfect sense let me know and I'll see about hunting up drawings on it.
