Apologies if this has been covered somewhere before. I've been reading TTSM ch. 4 over and over, and I can't quite seem to find a clear authoritative answer to what seems to me a basic question. Exactly what are the numerical dimensions of the transverse frames? Piecing together various internet sources and putting rulers to the drawings, I *think* I'm coming up with a channel of 10" x 4" x 0.5", at least admidship. Is that correct? At what point do the dimensions start to decrease, and how much smaller does it get before the construction changes to angle/reverse frame?

The channel frames in the midship area were of 10 x 4 13⁄20 x 4 3⁄20 x 13⁄20 inches. Of course many frames in this area were not of channel section (for instance at webs and bulkheads) so this is a generalization.

I just noticed that I asked this same question last year that I just asked you about in the other thread! TTSMv1 pg. 71 shows "10 x 4-13/20 x 4-13/20 x 13/20" in the figure (13/20 vs. 3/20 for the 3rd number). I was just wondering if you had an alternate source? Thanks,

Scott Andrew's drawing on TTSM pg78 expands on Ralph's May 5 '16 figures. It is not a symmetrical channel, the web is 10" deep, the inner flange is 4-3/20" wide and the flange next to the shell is 4-13/20" wide.
