Can't let Eben out-do me too much. Just finished my 1963 Sportsways Twin 38s rebuild project (1880psi). The 1/2" straight thread o-ring sealed valves are cool (as is the 0-ring sealed manifold). The bands and harness came from Alan. A whole host of folks on the board helped me with this project so thank you one and all. Mark
P.S. I understand from reading pasts posts that these tanks are quite heavy in the water. That said, I dive a 5mm full suit with farmer john pants, gloves, booties... here in the ocean. With a steel 71.2 cu ft tank I have perfect no B.C. buoyancy control down to at least 30 feet with a 26 pound belt (I weigh about 230 if anyone cares). So I am soliciting opinions on how much lead I should take off my 26 lb belt when diving these SW twin 38's (42s with 10% overfill) here in the ocean, all other things being equal. Of course I will perform some empirical testing but I'm just looking for a good place to start. Thanks, Mark.
