The message .com
from "Matty F" contains these words:

I believe I have invented the best way, but I was wondering if there
was a "proper" way that a perfectionist engineer might use.

Personally I either use softjaws for the vice, if I can find where I
last put them, or I lock a couple of nuts onto the stud and grip them.
