Gentlemen;
This is the best I can find so far. It is FAA manual on aircraft structures. Still digging https://www.faa.gov/regulations_policies/handbooks_manuals/aircraft/amt_airframe_handbook/media/ama_ch01.pdf (https://www.faa.gov/regulations_policies/handbooks_manuals/aircraft/amt_airframe_handbook/media/ama_ch01.pdf)
Thank you Richard. I strongly recommend that all read this as it has all the terminology we use in building our models but with an explanation of what each item is and what it does.
Very Good.
Jack.
