im in the process of building a homemade lab power supply. i just have a question about modifying an existing circuit. i have kindof narrowed down the circuit to this one

.my question is: how would i go about modifying it to make it variable from say, about 5 volts to about 30 volts(assuming im using a 40 volt transformer and appropriatly rated components) ive been trying to research on my own for a couple days but no luck. Thnks in advance!
