The table saw is the center of most workshops; it is the largest and most imposing tool in the shop. While it is an important tool, one could claim that table saw need not be on this list. However, it is an important tool and shows that creating a shop is not a matter of just collecting hand tools. There are jobs that hand tools cannot do as well as tools like the table saw, especially when there is such a wide variety of blades which can be set up and changed for so many different applications. Table saws create straight and consistent cuts. When setting up a table saw for a cut, one needs to set the depth of the blade and adjust the fence according to the width desired.
This is a hard question to really answer. I learn a lot from just being in the shop working. but, at the same time I learn and am exposed to so much more online and in books than I would be in my own shop. I had a hard time answering this question. Though I ended up saying books. Why? Because I learn more traditional hand tool techniques, visually see furniture construction(drawings and sketches), and I am exposed to different types of furniture styles, many older books were written by those who had done the same things for years, so they became very proficient at the styles they constructed in . All of these things combined give me a lot of information to take back into my shop. I could learn all of this from schools and from online content, however I feel I have enough basic techniques under my belt to learn successfully from a book, vs. when I first started when I was a kid. And I can buy several books for the cost of one class. Not to say classes are bad, I just don’t have the money to go galavanting all over taking classes.
Mike Siemsen literally takes you step by step (in "The Naked Woodworker"), going from "I've got nothing" to a full set of inexpensive used tools, and bringing them back into usable condition, then building your own bench and saw-benches. All for about $700. That will set you up with just about everything you'll need to make most furniture (moulding planes, plough planes, combination planes are ... extra-curricular). $700 spent on new power tools... doesn't get you nearly as far.
