I believe that the ability to make a setup that allow you to make a cut on the piece you are working on is what separates the master from the apprentice. Each piece that we make is a bit different from the next so being able to setup and fixture becomes the big variable that we have to figure out. Once figured out then the cut is made and we go on to the next 'problem'.
Might I suggest that you peruse some of the major catalogs and look at the tools available to assist in making setups and the tools available to make special cuts.

Trial and error
I never had book on setup, I just kept trying different ways till work.
I would look at photos on parts being machine.
I have photos hear on machining square bars in a steady rest. I also have few other setup here too.

There is a youtube channel of a machinist making a steam engine part by part (he's at part 8 as of this post, it is from a kit). He shows all sorts of fixtures and jigs and methods he uses to make each part.

The book Jigs and Fixtures by Colvin and Haas might be a good read. Out of print now, I think, but it should turn up on Ebay periodically. Carr-Lane used to publish a book/manual on jigs and fixtures in support of the related products that they sell and may still do so.

I never used a book either, however, if there were a book out there, I would like to buy one. Books always give someone else's experience which might tell one someting valuable.
If you click on the youtube icon while it's playing here on this site, it should go to the youtube site. Then you can click on his channel name, and there's a video tab to let you select the different videos he's posted. Each of these engine parts he's machining have different setups. I have no intention of building this engine, but his methods are useful for any future operations I may have.
That video is by Joe Pieczynski (Joe Pie). There are excellent videos on steam engine building by Keith Appleton, This Old Tony, and Blondihacks. All of those are just excellent series, both on the steam engines and general machining. I watch them a lot.
This channel by Joe Pieczynski i(Joe Pie) is one of the best channels to learn different machine shop techniques and trikes. He explains and them demonstrates. He is great and I suggest subscribing to his channel.
I am currently working on a 3/4" live steam Shay.

No problem, glad that (for once...) I had something useful to offer. In addition, the afore mentioned Carr-lane book is available $9.95 as a Kindle book from Amazon here:
https://www.amazon.com/Fixture-Hand...p/B01EBEHNMS/ref=mt_kindle?_encoding=UTF8&me=
It seems to me that at one time they had downloadable PDF of this as well, but it was not jumping out at me on the website. They used to send it to you on request, I had a paper copy years ago, but think I lost it in an office relocation or something. Perhaps they will send you a PDF copy if you ask for one. might be worth a try, all they can do is say no!
And there is some good info on their website here:

I got a notification that the post with the link to the jigs and fixtures book was deleted because:

The internet archive is full of materials well within copyright and the legal opinions suggest it is, in general, in breach of copyright. The problem is, they vigorously defend copyright claims and each copyright holder has to launch their own actions. As you can appreciate this is extremely expensive for the poor copyright holders yet the internet archive has vast resources. So if you don't mind screwing over the little guy, have at it, but please don't promote the site on the forum - it's a respect thing...

Quite bluntly, there are many people literally wanting 'something for nothing'
At the end of the day, publishing something is work-- and therefore no different to any other work- and.
should be paid for.
A Person steals, who without permission of the owner, takes or carries away anything capable of being stolen.
Even things like electricity come under this category. I was the guy that took people to court for illegally obtaining unmetered electricity. It was always explained that the debt was for a member of staff seeing someone using a light. The debt in question was the only for the consumption of ONE unit of electricity.
Restitution of the rest of the units used was always expressed as the mutual agreement of the two paries concerned.
That's the way that English Law was conducted

Assuming the site is correct, here's what they say:
Identifier jigsandfixtures00haasgoog
Identifier-ark ark:/13960/t8rb7239fLccn 38014454

I'm not suggesting taking/stealing someone's work but while you have to be careful, not everything on the internet is wrong or stolen.

Ken , If you want to learn Jigs and Fixtures, it will help if you understand
" 6 Degrees of Freedom" ( 6DOF)
Unfortunately , Most of the discussions on the net are not machining related and are pretty esoteric in Physics and or Robotics . As a retired Manufacturing Engineer, I taught my machinists this subject
I wish I could send you my Power Point but it is 55 megs in size .
The general stuff you read about , or watch on You tube shows the setup, but you need to understand WHY ! That is the secret of success ! Understanding 6 Degrees of Freedom allows you to do your own setups for some wild parts . I'll try to start off here with a major point of 6DOF from my slides without getting too deep i hope
--------------------
The single most important concept to Learn today is called 3-2-1
---------------------------------------------------------
----------------------------------------------------------------
Examples of a Plane are :
• A Table top
•Your Milling Table
•The Jaws on a Vise ( 2! )
•Surfaces on angle plates
----------------------------------------
2 P are 2 Points and define a Line o---------------o
1 P is a single point in space o
In the real world you see this
So in the above example there are 6 Degrees of freedom
You see the 3 -2-1 , and now a single opposite point is needed to control the object
This is the theory to understand for non-spherical objects, and use it to see how other people setups are made
Hope this helps
