Spindle Thread Protector - Internal Thread & Indexing

In todays project we'll be making a thread protector for a threaded spindle nose.
Starting with a piece of 304 stainless steel, the work will involve operations on both the manual lathe and the milling machine.
On the lathe, we'll do basic turning, and facing operations, as well as boring and internal single point threading of a 1-3/4" by 8tpi UNC 60 degree V thread.
On the milling machine, the part will be held in the Hardinge dividing fixture using a 5/8" arbor, and will be indexed every 15 degrees to create knurled features using a carbide ball nose end mill.

A huge THANK YOU for watching, and to all of the support that you've shown to me and this channel.

Who am I?
I'm a hobby machinist, with a passion for old machine tools and manual machining.
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.
My hope, is that by putting my work in front of much more knowledgeable machinists, we can all learn something new together.
