    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!!!!

    Much better idea! I can easily manage that. Thank you!

      Pictures! Take pictures! It ain't a documented war-crime without pictures at trial!

        Here you go Dave. Not to scale, but the shape is almost spot on

            Beautiful. Yes, that outer support bearing makes more sense than what I came up with. Thanks for the dope, I'll file it away for possible future use.

              David wanted pictures so here is the first one. I milled/ground/blasted/plasma'd but mostly Dremeled the back edge of the fixed planes to accept a tube for the pivot rod to go in. Tube ordered as I didn't have exactly what I needed. In the mean time I will work on the pintle/gudgeon (I had to look that up) arrangement to secure the outer end of the inner planes.

                Working the trailing-edge of the horizontal stabilizers is a much smarter approach to this problem that what I suggested, Steve. Well done, sir!

                  Hey, Steve. Would you send me drawings of the THRESHER's vertical stabilizers in relation to the horizontal stabilizers they were affixed to? Thanks. Want to have my 1/96 and 1/72 THRESHER's ready for Red Clay.

                    How about this? Of course this is what I did for mine. Not saying it is right. Scale is 1/48 and dimensions are in metric because it is just easier. Sorry.

                    It is centered vertically with the center of the stern plane.

                      Much appreciated, Steve. Just what I needed. I'll convert to 1/96 and 1/72, no sweat. Film at Eleven.

                        You are most welcome. Spent time today designing and printing the gudgeons. Got the starboard side roughed in. They will be secured with small screws thus allowing them to be removable. The tubing I need to install for the tip planes will be here tomorrow and once secured I can sand the gudgeon to its final shape and fill any gaps that may remain.

                          Nice work, Steve! And looking forward to the final result on those tail-feathers.

                            Echoing Dave, Nice work! That is a good recovery and smart with the screws, allows for easy replacement if required. A lot of our methods don't allow for easy replacement or repair of broken parts

                              Thanks. Yeah as much as possible I try to build my subs with the ability to remove and repair or replace in the event I prang something.

                                Steve, where did you find that the vertical stabilizers were on the Permits?
