As stated many times, I want to keep the boat original. However, I will improve slightly the transom framing. The cheeks are 7/4 (1 3/4") thickness, the lower bow and vertical supports are 6/4, the top bow is 5/4, and a two-piece construction. Both White Oak and Mahogany is used in a mix as well. I will make all the parts in 7/4 White Oak.
With tape and screws I guess I have enough for tracing.....
Not being sure what would happen with the outside shape of the boat with the transom removed, I screwed a 2"x4" to the between the battens and used a strap to hold the shape.
White Oak is soaking, and a steam generator must be built.
