Here are the first 3 largest midship frames, set up on the stem. I had a vertical stiffener on center line on each on, and at least one horizontal, about at the midpoint. The frames are 2 1/2" x 2 1/2" x 1/4" angle, and the floors are all 1/4" cor-10 plate. Note the transit to Charles' right, used for leveling and squaring each frame. This was before the days of lasers, which would make this process easier. But it wasn't too bad done the old fashioned way... we could get at least one frame up and trued per day. You can just see the gantry I welded up on the right side of the picture, it was 16' high, straddled the boat, rolled the length of the shop, and had a 1 ton electric hoist on a trolley. Indispensible. Next
