Centering square or rectangular stock in four jaw

[Doc]

Here is a short vid I did trying to show how I center stock in a four jaw. When you do this you need not have the indicator on center just close you will still pick up the low spot on each side no matter how far off center you have the indicator.  Hope this is of some use to some one.

Not a bad idea for stock which is fairly even in size , should save some time.
