    The deck is done, glued on both sides, added RTV on top of the glue to protect it on the long term against UV, it tends to make the glue brittle.

    The floatholders are glued in place, added some threaded holes to secure the floats.

    For now i started to add the rubber seals, next step will be adding all the M3 screws to keep the lexan hatches tight to the rubber seals.

      I had a small delay last few weeks, SWMBO wanted a new kitchen, she barricaded the cave, finished up this project a few days ago, so finally some more progress on the hatches,

      Brass M3 screws and stainless steel nuts to fasten the hatch.

      Made the screws pointy, more as a experiment to see if i can push them through the rubber seal at the deck, most work is cleaning all screwheads with the dremel to get a good surface for glueing.

      All hatches are done in one move, the pointy experiment prove to be useless, used a small drill to prepare the holes, much easier.

      Finally i could place all components which will be placed underneath the tower, for now i have to glue down both the scope and the schnorkel, this will be tricky, everything has to be in line and square.

          Thanks, it is still a lot of work, but i have high hopes she will see water within a few weeks, that is, testing if she is watertight.

              Manfred, love your work and documentation. Thank you!
              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                I can not say it enough, really great work! Your craftsmanship and attention to detail is amazing. By the way, your type VII looks awesome in the background. Can’t wait to see you get this new boat in the water!

                    Thanks Tom, as long everybody takes the time to document their build with the good and the bad we can learn from each other.

                      Nick, i've gained my craftmanship during the years by falling and standing up, being teased by David in the good sense, still hate him, the type VII is a special one, build by my mentor, which has reached roomtemparture, i decided to take it over with the intension to get it back in working order as a tribute to him.
                      Scale is 1:35, giving a length of about 2 meters and a weight of 17 kg, fully fuctional with 5 torps and all other moving stuff.

                        Manfred, Thanks for sharing the great background history of your VII. It has a lot of special meaning to it. Very neat. I ran across the videos you made some time ago about bringing it back to operational running. The working features on that submarine are amazing. Your friend was also super talented!

                          Yeah, that man had a gift for building insane mechanical things, i was lucky enough to learn the trick of the trades from him, made a simular type VII myself, learning each step in the process from my mentor, he never builded something for me, he simply said, you know how it works, you've seen it working, now, build it yourself.
                          At the end i had a working type VII, his best comment was, that looks like a nice type VII, i told you that you can build submarines.

                            Also a little update on the type XIIVb, she also smelled some water, a simple test to see if she was pressure tight, the testpool was allready in use for my Ko-Hyoteki.

                            She will need some weight from the internal stuff, only batteries inside and some valves, lead will be added inside the ballasttank if needed at a later stage.

                            Pressing her underwater and blowing through the airline to build up pressure inside the hull.

                            At very high pressure only this lipseal leaked, it will be replaced by a new one, you have to remember that the inside pressure will never be that high as simulated, in fact, i drive my boats pressure-less, due to use of a float on top of the deck, the pressure will allways equalize when coming to the surface.

                            Manfred.

                                Thanks Ken,

                                This was done last summer, this winter did some minor things on the boat, the rebuild of my house starts soon, so i don't think i can spent time inside the Cave, it has become a storage for all the stuff i had to remove downstairs.
                                At the end of May i hope to start up with building up the Cave inside the new cellar, the positive side is, my Cave will 4 times that big, finally i can give all the tools on the attic a permanent place on the workbench.

                                Manfred.
