Roll on glass to find the high spot.

Roll on glass and repeat till straight.
Done this dozenens of times over the years but read a few week ago about another method.
Drill hole in a 4 X 2 a couple of mm bigger than the hain shaft. put main shaft in drill, hold in the hole in 4x2 and run drill with some side pressure on the shaft. Not tried it yet but sounds good.
