Subject: RE: [PSUBS-MAILIST] No Machining Hatch Sealing Concept
Alec and Cody, You might like this configuration better for keeping the urethane from parting as easily. As you know, not all urethane is created equal. There is all manor of poured gasket products to choose from. In this configuration I've added a additional lower ring, between the others, and put larger weld beads on the upper sealing rings.
