Default Upscale Nose Cone Question

Is there any cross-reference chart for nose cone profiles that one could use for upscaling? i.e. here is an 5" ogive cone for a BT20 that matches the profile of this 9.75" ogive cone for a BT50?

For classic shapes, I used to go to the original catalogs:

http://www.ninfinger.org/rockets/ca.../711est128.html

http://www.ninfinger.org/rockets/ca...d/71dcen60.html

Today, the Semroc web site may have all of them.

I make my own upscales, so I just take measurements along the length of the nose cone, and scale those up onto my turning. Here is an upscaled Saros nose cone. (It will get tiny little fins added, which you can see on the original. The Saros used plastic parts for nose cone, fin can, and transition. It is my oldest rocket in my fleet -- built in 1976. Obviously this one had to be fabricated due to its odd size, but I did the same thing for the Estes Super Alpha kit. Estes had substituted a plastic nose cone that was not faithful to the original Alpha nose cone. Shown is my "60-sized" upscale of the BNC-50K.

Fortunately eRockets offers a number of upscales of Estes classics, but it seems like everything I want or need requires making them myself.
