When you re-string, rather than taking the string a little of the way through the hole and then winding it, take it all the way through the hole, pull it tight without kinking it, then put it through the hole again
This is interesting. Do you wrap around once before putting through the hole again?
Usually I take the string up to the tuner higher that the one I am stringing then kink here, thread through and turn many times. I don't have an issue with it going out of tune as I have a locking nut (well on my main guitar anyhow) though it is time consuming.
Perhaps you can clarify further?
