When drilling out a salt shaker interior on the lathe recently, I was having trouble keeping the Forstner bit traveling on center. I wondered if the old metal-working trick of drilling a large hole by starting with a smaller one might help. Sure enough, a 1/8"-diameter hole drilled though the axis of my shaker blank was enough to guide the tip on the Forstner bit to keep it on track.
