That image is where I'm stopped at the moment. It's a bit of a test-trial up to now. Right now. the dams are about 5in to 8in tall. The initial cardboard size has to be bigger than the intended matching dam, which is also bigger than the peer matching dam., which I wasn't sure about. And on the dam face there are 'indexers' and maybe bolting locations to accommodate. Once all mold segments are cast, I can trim the dams down. These dam areas are just for matching up mold segments. The actual mold surface is at minimum 3 layers of cloth and epoxy. I could go up to ten or make ribs where I decide I need stiffness to secure the form geometery. But since the form is so curvy, it's likely to be self-stable in most areas with out much ribbing.
What I call an indexer is a bulging feature on the dam face that keeps the mold segments in alignment. I'm leaning now more towards using clamps on the dams during actual part fabrication rather than bolts, since I find I can make indexers a lot smaller and more sure than I thought.
Eventually I may be able to keep the damns down to 2 or 3 inches, but I've not concluded on the results yet.
