I have set up a rolling ball clock in my kitchen and it worked for three days without any problems. However, this evening the motor jammed. I unplugged the clock and unjammed the rotor which had jammed against the little toggle which holds back the fallen balls for 30 seconds after each hour-drop. I don't know how it had jammed against this, but now the motor does not turn. How can I enter the casing to fix the motor? There appears to be no screws or clips. And don't worry, I'll unplug it before trying to work on it. Failing that, is there a source for obtaining a replacement?
