It's difficult to recommend a collection of "machining tricks" since the audience for such a thing differs so widely in their relevant experience. What's revelatory for one guy is old hat for another.
With all that said, I'll mention (please don't equate "mention" with "recommend") a few things that might bear further investigation...
This book...
https://www.amazon.com/Machine-Trade...s%2C219&sr=1-2
has lots of good information. Sadly, I think it's overpriced for its contents but that has a lot to do with my level of experience, YMMV.
The four volume set of
Gunsmith Kinks...
https://www.amazon.com/Gunsmith-Kink...s%2C221&sr=1-1
is obviously aimed at the gunsmith trade but does include things of a more general nature. Again, I think overpriced for what the typical homeshop guy might get out of it but, again, YMMV.
The best advice is to find a library where you can examine these yourself and decide if they are for you. Local metalworking clubs or gunsmiths may have copies they would allow you to leaf through.
