From trees to boards
Most lumber that comes into the shop starts off 'rough sawn'. This means that the lumber is cut into rough planks that are typically around 10 feet long. The milling process involves taking these long boards and transforming them into high quality finished material with square edges and smooth faces.
Many larger pieces of machinery are at work during this process, including surface planers, jointers, and chop saws, and table saws. This combination of machinery produces smoother workable pieces called and is referred to as 'dressing' lumber'.
