There is a book I recommend to alot. Mostly out of intrest/leisure

60 years with man and machine

A guy who started as a millwright in 1890. Was a touring magazine editor until the end of ww2

It's hard to find but it's a banger

For spesific methods (like jewelry making), there are pockets of web 2.0 vbullitin sites out there... kind of like hacker news

That jewelry site in question (i used it for metal casting knowledge)
