Andrew, thanks for the link. Interesting that another Nobler plan at that site has it constructed to fly clockwise. Unfortunately after reviewing the plans I have determined my project plane is NOT a "Green Box" Nobler but a Gieseke (sp?) Nobler. The hunt goes on
From the Top Flight kit? I just looked at my Gieseke ("blue box") Nobler plans, and they don't show the formers. Nor do the bits of punched-out sheet in the kit seem to have the ones that the formers were punched out of.
Nose and turtle decking was molded balsa, with this really odd scheme that had you whack the molded stuff in two on the centerline, then glue it back together at what used to be the outside edges. It took me fussin', fittin' and cussin' to get that all together.
The nose decking stays at a bit over 3/4" (25/32, if you want to be picky) until the former ahead of the wing. Then it tapers down to match the spinner.
Personally, if I were in your position I'd just follow Bob Hunt's balsa molding process. Free-hand the plug to a pleasing shape. Then start bending balsa.
