This is exactly why I uploaded the file:

Download it, print out a copy, and take it to the lathe. Useing
something that is easy to machine like PVC pipe or aluminum conduit,
practice, practice, practice. At first, read each step as you go.
Then when you feel more comfortable, do a few steps at a time, until
you can do it in your sleep.
The method works. I learned to thread using it.
You can buy ER4/5/6 or EL4/5/6 (size to fit your lathe) as cemented
carbide or you can grind your own HSS tools. I recommend you grind
your own bits for practice, using one of the carbide ones as an
example. Don't forget to leave clearance for the helix angle of the
thread. Don't try to cut threads using one of the el-cheapo carbide
bits. You will be frustrated because they seem to have no clearance
on any edges.
Hope that helps,
