Mike,
You might want to get a copy of Machining Fundamentals John R. Walker
I got mine on www.half.com for about $16.00, I found the companion workbook for $5.00 there also. Got lots of pretty pictures and high school level tests.
You may want to find a semi retired machinist and offer to sweep his floors, after a bit, you will be invited to help in some really amazing things.

Thanks for the tip. There are a ton of walker books available. Does
the edition matter. Thanks again.

Mike,
Not really, I have two different editions and they are pretty much
the same, except the CNC part.

This is exactly why I uploaded the file:

<
ead.txt>

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,
RA
 

Thanks for the advice
unfortunately I can't download the file.
Yahoo says something about them being restricted
But I am practicing and enjoying it
thanks again

The "restricted" means you have to join the group to access the
files. Since it's an open group, joining is effortless.

Did you try the above? Works for me.

The link got broken by Yahoo. Its a common problem. I'll try to
rejoin it here, but if that doesn't work (I won't know for sure until
I see the new message on the web site) you can cut and paste it back
together.

Congrats! I know how elated I felt when I first cut something that
looked as good as "the pictures in the book". :-)

Of course, you realize that few items really need the precision of
single-point cut threads (few of mine, at least). I just cut threads
that way because I CAN!

Do you have any unthreaded round stock left? ;-)

Actually I cut 9/16 12 coarse threads for a fixture i need for an
invention i am working on. the coarse threads are very forgiving.
A remaining issue is knowing when the threads are deep enough.
Taking the tailstock off to try the nut is NOT the way to go,
although with a coarse thread I found I could realign the setup.
Putting the fine edge of a caliper in the threads seemed to work for
coarse threads.
Seems like some simple attachments to the caliper could be made to
work for fine threads and even internal threads. Is such a thing
offered for sale or do I need to make it?
Thanks again for your help.

Thread wires?

yes thread wires will work
but i am looking for something simpler
for the thread I'm cutting, 9/16 12, shoving in the blade parts of
the caliper gives a number of about .475 for adjacent minor diameters.
Sure enough, when i cut the second one today down to that number, the
nut fit perfectly.
if i attached 2 razor blades to the jaws of the caliper, and knew the
numbers for even fine threads, I'd know just when to stop cutting.
