I’ve more or less gotten used to setting it by now Sylvain, but it took a while and I still have to adjust a lot more than someone who knew what they were doing. But I just wanted to get the idea out of my head, it was annoying me 😀

Laser. I once had this idea:

The picture was to show the concept; I didn’t make one.
I don’t know if anybody made one after.
About your center problem
I guess, if you rest you gouge (or a pencil) on the tool rest while turning the blank by hand, making a small circular trace, you will have a pretty good idea where the center is and how much you need to move the tool rest. Or am I missing something?
I avoid battery operated devices as much as I can and wiring near a rotating machine is best avoided.

Yes! I have a Jet lathe with a sliding head stock in a shop with a slanted floor (to a center drain) I used winding sticks to align the bed. Center points are close but not perfect. I have imagined a laser sight with a #2MT to let me align head stock/ tail stock centers. I would gladly buy such a device should you proceed past prototype.
