The Frames are 1/4" thick. - 5-layer plywood.
They were precut with a bandsaw, and from the looks of it, they did a careful job.
One of my reasons for going thru the process of verifying each frame for symmetry
is to locate center lines as well as the hull/waterlines on them prior to planking.
It is all part of the:
"Measure twice, confirm, Measure again just to be sure, wait until your hands stop shaking from too much coffee, Then Cut Once"
philosophy of model building.
I will apply each frame cutout to the face of the frame, using a few points of white glue, and then measure/transfer lines etc.
Once all is done I can start to notch the frames and Keel to suit.
More to come,
