Three Transistor Radio Baseboard Layout
For the baseboard, I am using a piece of off-cut wood, which I got free at my local hardware store. You will require a piece of wood 65 mm × 200 mm × 15 mm. It should have a smooth surface and square cut. They usually throw away pieces this small, and if there is a nice person there, then they may let you have it free.
I am all for using recycled components, and therefore you may decide to make your radio a different size, depending upon the components you have at hand.
Simply mark out the positions for the screws, and make an indentation on them using a punch and a hammer. You will need a 1 mm diameter drill to make the guide holes approximately 10 mm deep into the wood. Then finally install the brass screws and their cups. You will require ½-inch number six screws and their cups.
I decided to make this build in the same fashion as the ladybird book radio, using brass screws and screw cups. If you require more information, then I would suggest looking at some of my previous radio projects.
