Im beginner at scale modeling. Firs model im gonna make is 24-gun frigate "Pandora".

After just a few steps, im stuck and i need someone to help me.
I made stem (B2/2) and and stam framing (B2/6, B2/7 and B2/8) like on these pics.


and now i have problem with "stam framing".
There are 5 different shapes of stem framing, as you can see on the picture of framing types

I made all of them, and i placed them on the stem.
I can assume that "the shortest framing" goes on the rear of the ship , and the longest one, on the front, but what is happening between them.
Do i have to cut every single next frame different from last one, or i can put a 4 groups of same frames.
I cant find explanation of this in book (Anatomy of the ship - 24 gun frigate Pandora)
thank in advance
