Converting 2 pin plug into a 3 pin grounded plug

Figure 1. Illegal earth to neutral connection on an appliance. A break in the neutral wire will cause the appliance chassis to go live.

Your question shows a dangerous lack of understanding of the principles of earthing. As shown in Figure 1, your proposal exposes the user to lethal electric shock of the neutral connection breaks anywhere between your 2-pin socket and the local supply transformer neutral. Voltage will be applied via the motor and your neutral to earth connection to the chassis. In addition, if the neutral voltage is higher than ground for any reason - due to high currents in other circuits, for example - the fridge chassis will also have this potential.


  My question is can I get away with using a two pin ...


"Get away with"? No.
