    Was offered some detailed which I am grateful to get and will use and not share per agreement. Thank you.

    The casing has these massive undercuts to tuck in those open torpedoes. Thinking we may need three-way split. a full lower half, and then a left and right top half? David? So, your definite on 1/32?

    Either scale is good but the 1/24 might be a little roomer inside around the WTC? But Dave you have to decide scale early on in the process naturally as you are the 'primary shipyard'. and I am ust the lofting dept...lol. We can also all go over this in private emails and move this portion of the todays build to a new thread? I don't mind transparency, the resources of advice here are an embarrassment of riches already. :)


    'Norbert Bruggen did a model of this". Norbert? anything from your build you could give advice on if you wished you had done something differently perhaps in hindsight?
    Naw. Keep it on this thread... I'm sure the originator won't mind too much. And if he does... **** that guy!

    And hell yes. Open source; no secrets; share the wealth; blab away. It's the objective here (and it always should be this way) is to spread the word. Only selfish idiots of poor moral fiber work to keep 'secrets' from fellow Craftsman.

As the rubber captures all detail, don't be shy about putting in such no-no's as limber holes, plating, panel lines, oil-canning, etc. The rubber will capture all (even finger prints!)
      ok got it, and will be then in1/32

                I bet you were that kid in school who, in the cafeteria yelled, FOOD FIGHT!!, and promptly high-tailed it out the exit door to prevent any of it from getting on you.

                        Going to printer to enlarge plans this morning. The CB submarines used a 450 mm (17.7 inch) caliber torpedo. So, adjust accordingly. I'm sure you have the appropriate torpedo in your quiver. I will need to make measurements in the printer store where they have the self-serve enlargement printers.

                        Will see if 1/32 scale will work - thats my scale target. I want to use off the shelf existing components wherever possible. It could be 1/32 might be too small for the 2-inch WTC. We might have to opt for 1/24. Will get back to you after returning to the printers. Stand by

                          I'll defer to you on what scale we settle on, Steve. Better too big than too small. Ideal would be a scale that results in a mean annular space of at least 3/4" between WTC and hull.

                          Regardless, I'm compelled to scratch-build new torpedo masters. No biggy.

                              The 1/32 scale is do- able. We will go with 1/32. The waterline break affords a curved flared out contour allowing a big gap wide enough (if the hull break is at the waterline) to basically shoehorn in a 2-inch wtc. Tipping front up and in and sliding back. the drawing seems to suggest that's very possible. Like loading a cartridge in a rifle backwards. Magnet connects should make easy & sure to shaft and stern controls. No bow planes. If you think the scale should be different, time to say now.
                              a
                              It's a great size the hull lines are widened a skosh more - 1/4 inch more an 1/4-inch deeper for added volume that no one will ever notice.

                              I am starting off on the template sections tomorrow and its 'get going'.

                              How long is this 2-inch wtc Dave?

                                Go with 1/32. As I'm doing the layup, I'll strive to make the above waterline structures paper thin to minimize displacement of those structures. If I put the motor in the wet, I'll be able to size the 2" WTC to fit.

                                Proceed, sir!
