In Episode 3 of Building the TotalBoat Sport Dory, Lou is taking us back to his all-important drawing board, where he explains the importance of all the specifics of the drawings needed to build the dory successfully. In this episode most importantly, he shows us very specifically how to measure the dimensions on his original drawings, and how to transfer those dimensions from the drawings to his "Table of Offsets". Once these dimensions are transferred, the Table of Offsets now has all the dimensions of each plank, at each station, and gives Lou all the specifics he needs to build the dory. Lou shows us that it is this Table of Offsets that is really his index and his guide for actually building the dory, more so than the actual drawings of the planks and stations themselves!
