    One of the things that didn't work on Sunday was the periscope system. On checking it, I discovered that the plastic manifold beneath the syringes had ruptured. That's one powerful little pump driving the system and it completely overpowered the manifold. (It also launched two of the periscopes when it was originaly run as a pheumatic system). Hence the new, bullet-proof manifold. Lovingly crafted in 15 minutes using a blow toarch and some very scared copper pipe. It ain't pretty but it does work.Click image for larger version

        Can you control individual cylinders to raise/lower each mast?

        Might have been simpler to use a single cylinder to raise/lower a platform holding all the mast together.
        Make it simple, make strong, make it work!

          Hi Scott,

          How did you get your stunning tiling look?

          Did you apply masking tape and color variation in the paint?

          Grtz,

            Initially I planned to use two pumps. One to raise the attack periscope and open the torpedo doors and a second one to raise all the other masts. Also looked at a rotary hydraulic switch that would have given me twelve combinations to raise and lower different masts. When I did the initial trials it became apparent that a single system operating all the masts would suffice because each mast offers slightly different resistance and operates at a different rate. In practice that means that the masts appear individually untill they are all up and then retract one by one untill thay are all down. By stoping or reversing the pump I get different combinations of masts to deploy. Working quite well now and since changing from pneumatic to hydraulic there are no more unintended mast launches.

              Hi Bart,
              Exactly that. It took some time to decide on the pattern of tiles because every photograph that I looked at showed a slightly different pattern. The tile joints get slightly larger towards the rear of the sub. I don't know why; it just appeared that way in some of the photographs, so I replicated it. Before removing the masking I painted about 20% of the tiles a slightly darker balck and about 5% in blue/black just to get some variation in them.

                  Scott I have a daft question.....if I may......

                  What are the dimensions of the sail on this thing? Preferably the length and width at the base.

                  Many thanks if you could let me know.

                  Peter

                              Holy Smokes those are exciting photos. Well done sir, well done.
                              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.
