1973 V-20 transom project w/photos

Thanks for the imput! Did I mention I an closing the whole transom in and adding a R-4 Bracket from D&D Marine?
I am thinking of laying up 1/2 inch on a curved jig with a sheet or two of 1708 in between. I can just screw them to the contour jig and unscrew them as they dry and add the next piece of 1/2 inch--whatcha think?
