I think Wolfie that Tel has largely answered your questions regarding my books and web site.
I would though add that your comment about purchasing a Morse taper blank is obviously, at this stage, the way to go if you are at all hesitant about making your own.
If though you get into making workshop equipment it is likely that there will be occasions where this is not appropriate. For example, in the case of the milling cutter chuck, chapter 13, concentricity of the taper and the working end (the cutter chuck) is vital, and is best made as one piece.
At some time you may like to make an item with an internal Morse taper, such as Tel’s dividing head. In this case, unless you purchase an expensive Morse taper reamer, machining your own taper is the only way.
When you have completed the die holders, attempt to make a taper using a scrap of steel and if it works out I am sure you will eventually find a use for it. You could try either the method mentioned above or try the method I suggest in the book.
