Default 12V Circuits

Hi,
what i want to build is a control device for my comm lathe, so i can run it off my PSU (12v DC) but i dont want to run it that fast normally around 5v is my preference, i was thinking an adjustable circuit of some description with a rotary pot to adjust voltage.
1) is this possible to achieve?
2) is there a circuit diagram for this available somewhere on the net?

3) am i better off making it someone elses problem?

Rob Storey
