  1. Cut a piece of wood 10cm long
  2. place two crocodile clips on the piece of wood to hold a ruler in place  
  3. open the crocodile clips and place a ruler through the centre of them and clamp it down
  4. Now pull the ruler as far as you need to measure and draw a line to accurately measure any measurement you need. 
  5. This will give you a straight piece of wood every time
