I certainly haven't done hundreds of them, but I've had pretty good luck with a v-block (u-bolt) arrangement to hold the steerer relative to a center-line.
The fork below was whacked over to the left and having even a such simple gage as this helped be get a handle on the direction and extent to whick the fork needed to be righted. Still, it's best to proceed slowly -patience is key, because it's not hard to over do things.
I just not feel confident/practiced enough to employ Sheldon's method.
