Great info - thanks, everyone! Josh, your drawing is the only one that I have seen that shows the
diameter of the hub (1.81"), which was the dimension that was giving me fits. And it also showed that they were true cones (with truncated tips) that intersected the fin root. Rocketguy, the Thiokol brochure clears up a question that arose during my research. Buzz Nau's
photos of the Nike-Tomahawk show a version with an enlarged payload section. That was the first time that I had seen such a configuration, and it isn't mentioned in
ROTW. The Thiokol literature confirms that this was one of the standard versions of the rocket. (Now to find a dimensioned drawing of that section...) The
ModRoc article and the Alway data provide enough remaining details for my present purposes, anyway. I did already have a copy of the Quest Tomahawk plans (as a matter of fact, I have an unopened kit, too), but it didn't show the hub's diameter at the base, just its height. (Quest's molded plastic fin can for the kit is too small for me to be able to measure that feature accurately.)
As part of my project to clone every FSI kit, I'm building a clone of their 1/8-ish scale N-T. And just as I would have done if I had an authentic kit, I will be enhancing the build with scale details that weren't provided with the kit. (I'm doing that will all of my clones of their scale kits. FSI encouraged this in their instructions, if the builder wanted to go beyond a basic sport scale version.) Now I just need to figure out how to make four identical 0.2263" wide by 0.298" tall cones, and then split them evenly in half!
Thanks again, I think...
MK
