Accuracy can be very good. I have gotten my clock to be accurate to within
less than 5 minutes off in 24 hours.
And I haven't even gotten to extreme fine tuning (I am still adding and
subtracting bricks, eventually I will get to 1x1 plates. :-)
The design of my clock is unique in that I am using a pendulum to control
the accuracy, but power is coming from a new 9v motor, hooked up to a train
controller set at the lowest power setting. Those motors are strong.
The gear works is a modification of

I have spent most of my time on getting good accuracy, and a good looking
enclosure designed. Hopefully I will get some pictures up in a week or two.
