Here is the part of the build project where I have to actually pull out some of the kit instructions to ascertain the proper placement of fins, launch lugs, and whatever other details there happen to be.
Setting to work with a precision-sharpened pencil, fin spacing guides, ruler, and a length of metal shelving standard to draw the longitudinal lines, I soon have a set of tubes all ready for assembly.
Time to fire up the ol' glue pot...
