    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.

    Overall top view.

    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.

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!

    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.

    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!!!!

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...

    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.
    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.

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