HowTo machining lathe threading singlepointthread acme

In todays video, we take a brief pause from accessorizing and upgrading the new lathe, and work on a job for a client!
We will make a tailstock feed screw for a Leblond lathe.
Starting with a piece of 1144 stress-roof steel round stock, we will machine the entire part from start to finish using manual machine tools.
Basic operations covered in this video include; turning, facing, grooving, turning to an accurate shoulder, and more.
We will also need to hit a critical diameter with a close tolerance of +.0000" -.0003" (spoiler alert, we nail it ;)
For the most important feature, we will be single point threading a 5/8" - 8tpi LH ACME thread.
And then a brief stop at the milling machine to cut in a woodruff key seat.

Machines Used:
MSC / Prince 9517350 - 13x40 Manual Metal Lathe
Bridgeport Series 1 J-head Variable Speed Milling Machine

Who am I?
I am Hersch!
I'm a hobby machinist, with a passion for old machine tools and manual machining.
My favorite place to be, aside from with my wife, is standing in front of the manual lathe.
I like to fix up and restore old machines, make my own tools, and I also take on small jobs fixing, or making parts, etc for others.

Why am I here?
I am here to share and learn.
Being self taught, much of my limited knowledge, has come from others sharing their experiences online, just as I am doing now.
This channel is my way of giving back a bit of that which I have gained from others, while at the same time hopefully being able to learn even more by putting my work in front of far more knowledgable and experienced machinists.
