What is the procedure for broaching on a lathe? I thought it was done
using
a press. Since I have no experience with the procedure, could you be more
specific?


This is easy to show, hard to describe. In this case, for 1/4" square, mount
a 1/4" tool bit in a tool holder so its aligned with the axis of the lathe.
Sharpen bit so it cuts on one side. With the lathe off, and your part held
in a faceplate, four jaw, or whatever, rock the carriage back and forth.
Move cross slide to incease depth of cut. I've seen an article on this
somewhare, maybe someone can post a link.

Same idea can also be done on the mill, but the quill lever is nowhere near
as stout. easy to break something in your mill.
