Making The Ribs For the Big Hull

Because of delays in building tools to build parts for the boat, i desided to go with a faster construction method, at least for the main hull. I'm going to make it a stretched octagon, not a round cylinder. The reason it's an octagon and not a square is because i wanted the maximum width and height in a boat hull shape that i could turn over and still get the new bridge crane over. The width is constrained by the 8ft rule of what can be trucked down the interstate to the ocean, at least without special permits. Besides, i want a long and narrow, well proportioned boat hull, not a wide barge.

Here's the jig with no rib steel laying on it. It will form an octagonal rib 7.5ft tall and 7ft wide (outside dimensions).

Here it is with the 4ft long top and bottom sticks, and both 5ft sides on it. I have not cut the 2ft lengths yet.

I adjusted color and/or contrast on both pics. The one on the right was badly over oranged by the camera, i have no clue why.

Here's where the 2ft lengths will go. Note both pieces are pulled out to stops, and then slid down to this corner to a stop of each. Click image to get a bigger pic in a new browser tab.

This is how the 2ft length will meet the 4ft and 5ft lengths. I'll also place a gusset on the side opposite my toe, on the inside of the boat hull naturally, because there's just not enough space to weld on that joint no matter how it's sliced. In my opinion.
