I have a King KC1022, very similar to the Grizzly G0602.
-I replaced the motor with a DC treadmill motor. This gains variable speed, no more belt changes.
-I replaced the compound with solid tool post. This gains much deeper cuts and parting off at >500 rpm
-Properly preload the spindle, removes chatter (someone had been at my spindle adjustment before me)
-Added a 5C collet chuck, a joy working with round stock now. You can remove a part, flip it over and still run true. Bought an inferial set of collets, then added metric ones as needed from KBC Tools.ca
-Added DRO's
Overall a solid base to work from. You can buy these new in Canada from King, KBC Tools and a similar one from BusyBee. Unless the Canadian $ goes to par, buying in the US is generally not worth it.

If that's what you guys call tuning. Then I'm 100% on board. Been there done most of that. No bearing adjustments or motor replacements though. Dro in process.
LOVE my 5C Collet Chuck. It's the only one that lives on my lathe more than on the shelf.
Thanks for the info.
