It sucks when you have only enough stock to make a part in your lathe. Needed to use all
1.52 or so inches of some round stock I had today. That extra operation of turning it
around vs just drilling, boring, profiling and parting added extra time to what should
have been a quicky. I'm getting better at dialing in that 4 jaw independent with
practice.

This is my on topic post of the day.

Well, at least you can do that, as opposed to "nope, can't be done,
better go get 12 more feet" which really eats up time for the unskilled.
So consider all the time you saved on travel...

Have you tried using two chuck keys, so you can adjust two adjacent
jaws at the same time? It makes an incredible difference.

Teenut's dialing in technique:

Quick tip for setting work true in a 4 jaw in two revolutions!

(I learned this, setting up roll turning lathes with 108" swing and a
jogging speed of two to four MINUTES per revolution.)

1. Revolve the work through one revolution..noting the TOTAL swing of
the indicator needle. Bring the spindle to a halt at the MIDPOINT of the
swing and ZERO the dial to the needle.

2. Revolve spindle to bring jaw one to be "on the plunger". Adjust jaw
one and jaw three to ZERO the needle again.

3 Rotate 1/4 turn and adjust jaws two and four to re-zero needle.

Job is done!
