True it this way...
True slightly, as in less than 1/4 turn per nipple, to whatever side you prefer, then remove and flip the wheel 180 degrees. Repeat until done. You'll never be concerned with playing with the adjusting nuts again, or when you're finally done readjust your stand. My preference is to leave the stand the way they end up after a year, 2-3mm off to the left, and just flip the wheel. Always follow up with the gague to be absolutely sure if you're still learning. Usually I use the gague to be absolutely sure it's true, but rarely do it wrong.
