Oh I always use the indicators.  I get everything I do as perfect as I can.  My trade is Machinist and I worked in job shops for 8 years.  We didn't make a lot of new parts in groups.  Usually one off but mostly repairs.  It was very interesting work and probably why I like messing with the skis.  With the 4-jaw chuck you can move each individual.  3-jaws just grab all the same and you can't adjust so accuracy is out the window.
