Thanks, Dennis. I have a ’22 CBC, but it’s a little delicate and I’ve never wandered through the roof section. I’ll have to check that out. ==========================
Schuyler,
The drawings of the ARA standard lumber sections are on page 367 of the '22 CBC, in the first pages of the "Car Construction" section. The same drawing was reproduced in several other CBC's, 1931, I think, and 1940 for sure.
