I often use two indicators. One near the chuck and one at the end or on a face. As you have a qctp its worth making up a indicator holder for it, quicker than a mag base.
I dont use 3 jaw as mine is bent, I can dial in 4 jaw just as quick.
Last thing is a more precise dial guage. My good one is 0.002/div. I think the needle has the same range but somehow it does make a big difference!
This was not the intended use for the adjustable links... Couple of changes and it will be! (Lathe is set up for milling right now so ignore the qctp holder being in the vice..)
