There seem to be some differences between the 2 kits even though they are the same scale. The cross-section kit has been simplified in a number of ways. Like most Model Shipways kits that I have built, the plans offer lots of detail and it is up to the builder to determine how accurate and detailed to build the kit. After doing my plating, I can say that getting a consistent 1/64" overlap would be really difficult for me. Cutting 1/32" from the width is probably doable. The cross-section was designed (in the instructions) to use 1/4" wide plates with 1/32" overlap. As long as the plates are consistently overlapped it will likely look OK even if it is not completely scaled accurately.
