This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

It's interesting they called first angle 'British Projection'. I can see calling third angle 'American Projection' cause of ANSI, but it is still kinda odd.
Thank you for sharing. I’ve studying everything included in these notes, I understand it all. And in the years that I did study this, not one of my excise books of notepads was nearly as detailed. I’d ‘look up the slides’ or ‘google it’..
Science Technology Engineering Art and Mathematics in motion.
Thank you for sharing. These are beautiful notes.
You're welcome. I guess you're ready to inspect WWII-era military aircraft!
Great looking HAD drawings.
I wish I had an ounce of his talent.
Wow! Thanks for posting this. I personally find this VERY interesting.
I think it's really interesting too, but he was my grandfather, so I'm biased. I wasn't really sure how interesting drawings of screw threads and gauges and calipers and such would be to other people.
Those drawings are beautiful. I wish I could draw like that.
Me too. He tried to teach me some when I was a kid, but I just don't have the aptitude for it.
Dude made his own pocket ref.
I grew up in a sheet metal fabrication company in the US. It's wild to see drawings of measurement tools I'm familiar with from 80 years ago. I had no idea these designs were this old. This is so cool, thanks for sharing, OP!
Really cool item to have. Ty for sharing.
These are beautiful and way more than just mildly interesting.
The sacred texts!
That is very impressive! I really like the detail view of the gauge indicator
This is so cool!
And it seems to ge written with a fountain pen. The times where people could write properly, beautifully, and made things to last.
I kind of regret being born in such a wasting consumption focused society...
Definitely a fountain pen. This was before ballpoints.
