As the name suggests this is an instructable where I will endeavour to show you how to make a clock tick backwards and also to draw your own clockface by hand.
Step 1: Step One
And I forgot to take a photo of the clock before I started working on it...sorry...
You will also need these tools:
Mathomat (if you don't have a mathomat you can use a ruler and something round to draw circles)
Step 2: Step 2
You can use the plastic cover from the clock as a handy bowl.
Once you have taken the hands off carefully extract the mechanism housing from the rear of the clock (you may have to sort of pop it out over a ridge or perhaps push back a pin or something)
Then, again carefully, open the back of the clock.
It should look something similar to this (your clock mechanism may not be propped up against a lighter as is shown here.)...
