    You're spot on, sir. The larger 1/96 model had the room for independently operated stern planes -- one set inboard, the other set the full-flying outboards, each set with their own operating shafts. The smaller 1/144 model only had room for a simplified arrangement which ganged the inboard and outboard control surfaces on a single operating shaft -- a cheat.

    Practical and sensible as always sir. Makes total sense now that I realize you were displaying different scales in the same post. So based on the 1/96 boat the inboards were not supported by a "tooth" as I call it?

      That's right. The inboards (on my model, anyway, not sure about the prototypes) did not have an outboard bearing, supported in whole by the operating shaft.

        Not sure where people are getting stern shots of the SSN-21 class from, (let's see the reference) but this is the stern of a VA class with a split stern plane config and it looks completely different from what's being discussed. Here's a VA stern shot:

          The title says, "... USS JIMMY CARTER". A SEAWOLF class design lengthened for spooky-poo stuff. Where does the VIRGINIA class come in here as source material for Steve's model? Or am I all wrong here?

          VIRGINIA ain't SEAWOLF. Duh.

              Well let's see my references. MY EYEBALLS, I saw Seawolf and JC in drydocks while they were still in Groton. Yes that is a Viginia stern and no it isn't the same as a Seawolf. And to cover the other bases, previously qualified COW/DOOW on 88's and previously qualified pilot/copilot on VAs.

                This is what I am going with. Drilling the additional shaft hole in the fixed planes for the tip planes and keeping it straight will be a bi**h but I am going to give it a try. Ehh, it's just plastic.

                  Steve, whatever you do will be fine. The hull is big enough that it shouldn't be too much of a problem, but if you decide to stay with what you have, it will still work.

                    (You do know... Steve!... this is pay-back for making me add those vertical stabilizers to my THRESHER models).

                      The picture is kinda misleading. The cuts have already been made. Doing a little Bondo work where I joined the tip parts together and then time to do some careful drilling.

                        Okay, i didnt see a picture in your post Steve.

                        In answer to the previous question of a "tooth". A little further research shows that there is a pintle "tooth" bearing at the end of the stabilizer. I can upload a sketch later.

                          That would be appreciated, and a much better engineered mounting than what I provided the inboards to my 1/96 model SEAWOLF.

                            Thank you. I am at a point where I could easily add it. Still trying to figure out the best way to drill the fixed planes for the pivot rods for the tips.

                              Lol. Yeah... I never dreamed the Seawolf would have stern planes like this and they are more tricky than verts. Hey, you don't have to add them as it wasn't until just before her fateful voyage that the THRESHER even got them. Clearly it would have been easier if the tail section on the Seawolf (JC) had the provisions for the separate tip planes but I can do a lot with a drill and if it doesn't work maybe I can modify the file and re-print it. I need to rig a fixture to hold my drill secure so I will have to channel my inner David Merriman to come up with something that will work. Ohmmm...

                                Don't drill, silly -- even if you align the drill motor perfectly 'bit drift' will still manage to kick your butt -- that's going to be a very long bore!

                                Do this instead: mill/grind/blast/plasma a channel into one face of the horizontal stabilizer over where you will install a length of K&S tube. That tube will sleeve the outboard plane operating shaft. That ugly trench can be as wide and deep as needed to accurately center the tube with shims. Once that tube is centered you back-fill the trench with Bondo or thickened laminating resin and block-sand the surface back to contour. No drama, and the caveman milling/grinding/blasting/vaporizing is a great stress reliever (for you, not the model).

                                Naw! Too late. You already dragged my substantial ass down that rabbit-hole; I gotta put those verticals on now. Gee, Thanks!!!!
