sof to s&g

get some of that free adhesive shelf paper from terry hanson, stick on a sof panel and mark out the seams. lift off and use as pattern to cut out ply. make some temp forms for rocker control.

or s&g to sof:
take width measurements for ea beam location. make top frame to suit dims. take sectional shape measurements at say 4 or 5 locations and make temp ply sections to hold stringers at the chine. add stringers on temp forms and bend ribs to hit stringers. remove temp forms. same approach as many sof's except more forms used for more exact shaping.
