A component mill for producing wooden construction components has a pair of input rollers spaced from a pair of output rollers, wherein each comprises a pair of vertically-stacked pinch rollers. The mill has an overhead X- and Y-axis track system for scrolling a high speed router bit dangling underneath a high speed motor in X- and Y-directions as the input and/or output rollers pass a board for trimming by the spinning, and perhaps scrolling and not stationed still, router bit. A control system controls the input and output rollers, and X- and Y-axis track system in concert to form a selected design of a wooden construction component output from an inputted board.
