    Yes, the propeller picture. Fortunately I had already started the work, and your photos validated how the dunce-cap is shaped as well as the propeller is not of the controlled-pitch type, as reported by one source I read.

      • I hope that you are wearing some substantial foot wear this time around. Just sayin'

        I have been giving the front sonar dome some thought lately. This is the current idea which uses thin tape overlaid with bare metal. Its OK, but the tape is a bit too wide. I'm going to experiment with waxed cotton thread as for formwork and see how that looks. Any other ideas are welcome.

          thin adhesive strips followed by a blast of abrasive grit within the tape matrix. Remove the tape strips and wa, la: dished in GRP sonar window.

          • That's a good idea. After painting the tape and bare metal looks clunky. I've been experimenting with etched brass. Looks a lot better.

            • You're getting giddy on us, pal; like a kid in a candy-store. Seems you are enjoying your transition from hack to real model-maker.

                I agree with your conclusion, which is a shame because the tape looked so cool pre-primer. Great idea.

                On the final hull, will the sonar windows be recessed or slightly raised?


                *EDIT* - I'm with Tom on this - the foil look, especially the kind of "wrinkled" texture that those horizontal lines add a ton to the overall texture of the boat. Almost sort of like the skin on a B-52 when you look closely:



                I don't know what it is about those silver colored sonar windows, but I've always really dug that look on the vintage Soviet boats. Perhaps you could build up a few layers of primer, then lay out a grid of horizontal & vertical lines made of brass or foil, and then do as David suggested and blast the remaining area with an abrasive?

                Either way, keep doing exactly what you're doing. I just get more and more excited every time I open this thread.

                • Those are nice ideas for the sonar. I see the clunky that you are talking about, but having that molded in adds to the look of this sub. At our local craft store, there is a foil (gold, copper, aluminum) maybe that would reduce the bulkiness?
                  If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                  • That's the foil that I used. Was hoping that it would be a little bit stiffer and mute the tape lines but its very thin and conforms almost exactly to the outline of the tape. I've found a better solution, I think. Workimng on that today.

                    • look forward to your solution!

                        • Love watching you do that voodoo that you do so well.

                          • Oh,oh,oh excited squeel. Propellers! They look great even without the dunce caps.

                            The third, and I hope, final answer to the forward sonar dome. This one is thin brass sheet beaten into submission and stuck to the front. I still have to refine the edges but it certainly looks a lot better.

                            • That sonar window is beautiful. Please share with us riff-raff how you did it.

                                Just curious, what is the sonar unit in the sail? It would appear that it rotates. I think I remember reading that our sets had to be “steered” as well. It is just interesting considering the multitude of different sonar arrays on & around the bow.
