Step 2: Production
After Measuring all of them out use a saw or band saw, as long as it keeps the Wood Square it is okay to use.
To find the centre of the front face I drew lines using a pencil from corner to corner. The point where the lines crossed was the centre because the front face was a perfect square and this is where I drilled the whole for the speakers to sit in using a hole cutter. Depending on how big your speaker cones are, mine were 66mm in diameter.
The Volume Knob and On/off switch are going to come out of the front, so i had to measure all of the distances between each button and switch. be careful to measure the distance from the top of the base panel to the bottom of the circuit board.
