I have a long PVC pipe and a use an old crown race as a driver and turn the whole thing upside down and give it a few hard whacks on the floor. Does the trick every time. The only trouble I have had was actually seating both the crown race AND the driver along with it. That sucked. It was a cheap fork that had a lot of height on the race and I did not even think about it before pounding it on. ^ Don't tap, give it a whack ( but not while resting on the dropouts!)
