  • Ah... now I see your cunning plan. Take a simple situation and COMPLICATE IT BEYOND BELIEFE! I have a good friend who reminds me of you. He is a professor of gynacology who did a certificate in diesel mechanics so that he could work on his own trucks - unfortunately it takes him three times longer to do anything mechanical on the engines because he has to go in through the exhaust pipe!

      • From the Fleet Sub Operations Manual of 1946 please read as it fully describes all fleet boat air systems:

        https://maritime.org/doc/fleetsub/air/chap1.htm#1A

        This is the complete Wikapedia, Fleet Sub Manual on Steroids!

        If one has several months spare time you could study the entire fleet boat manual!!! Best of luck

            I sent you a PM. Better read it.

              • Hi David. Really interesting stuff, your markings. How do you do in the first photo? Are you cutting the tape to shape the lines?

                  OK, I got a length of 2.5" Lexan in the shop. How about this: five inches for the after dry-space (the three-motor motor-bulkhead is shorter than the other motor-bulkheads); five-inches for the ballast tank (even with the big gas bottle you have nearly nine-ounces of ballast water); and a six-inch long forward dry-space for the battery (which can be shortened if you go with a tighter battery pack if you wish).

                  The above comes in with a cylinder length of seventeen-inches (two-inches longer than the fifteen-inches you stated, but you can cut off some of the forward cylinder to make the fifteen-inches if needed).

                  I don't want to cut Lexan till we agree on the division of the three dry spaces (by the way, the seventeen-inches accounts for the thickness of the forward and after ballast bulkheads). So, Scott, get back to me ASAP and I'll start in on the two SD's (one for me, one for you).

                  Here's the 1/72 FOXTROT and its three-motor SD -- pretty much like the unite I'll be working up for our ZULU's.

                  • Thanks Mate. I suspect that because of the tight internal diameter, a portion of the ballast tank will be above the design waterline - maybe up to a third. I can get by with a forward battery space of 5 inches so I'm leaning toward 5 inches for the aft space; 6 inch ballast tank; and 5 inch forward space. What do you think?

                      Very good. 5" X 6" X 5" it is.

                              • Scott,

                                OK, got your ZULU kit broke out and examined. First, pal -- a big improvement over your neat little ROMEO. You are on the 'fast' learning track, sir! Good job. And no significant warping of the GRP hull parts. And I love your breaking the upper and lower hull at the waterline.

                                Speaking of waterline ...

                                ... A 2.5" cylinder is way too big. One-third of it will be out of the water in surface trim. So, our SD's will be of the 2" flavor. I'm currently working on a gearing that will give us the three propeller shaft outputs from one single motor. Trust me, it will work. Pictures soon.

                                A 6" long ballast tank, using the 2" SD cylinder -- even accounting for the displacement of the gas bottle and conduit tube and other happy horse-**** inside it -- will give us a floodable volume of six ounces. By the way, I came up with the same above waterline weights (assuming that the GRP and resin have a specific gravity close enough to 1 as to not matter) as you did. We're on the same page.

                                I'm cutting Lexan tomorrow -- so get back to me if you have any heart burn with this arrangement, Scott.

                                David
