    atic: 1:35 Bronco XXIII with interior

    After finishing my VIIc build I decided that I need another cut-away challenge. So I'm going for a 1:35 XXIII boat based on the excellent Bronco kit. Minor problem....the model has no interior. So I'll make it myself. Started designing everything within the CAD, based on books, plans, and photos. Firts impression....drivetrain with stuffing box, thrust bearing, belt drive-coupled creeper motor, main clutch, e-motor, Diesel clutch and the MWM RS32S Diesel. Tedious, but the first fitting in the virtual pressure hull only required minor corrections. Good sign...Click image for larger version

          Added the blower for the room ventilation. Here starts the guesswork because plans and descriptions are not clear about position and size. Also added the first sketch of the air induction and the air exhaust masts. Again, plans are not coherent...again, some room for guessing.

              Maybe of help?
              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                Awesome.....THX. That's U-Hai (S-170), an overhauled Nazi sub that was used as training boat for the post war German Navy....



                The Diesel air-intake had been re-dedigned. So this might not be the actual XXIII configuration. But it gives good hints!

                    The new photos of the induction masts booked me into a complete redesign of the masts and the respective piping. Again, allot of guessing, but the green pipes are according to the ventilation plan and comply with the pics...tedious.

                      Holy hell... This is going to be an amazing model, when completed, digital or otherwise!

                            More detail work. With the help of the iron plan of the Type XXIII I added the machine bases and floor. On the starboard side, benath the floor plates and parallel to the Diesel was the lubricating oil tank.

                              If you're planning on printing this, it'll probably pay you to buy your own printer with the price of them these days, versus bureau costs.
