Here is one of the critical things when you make the holder. You need to have the tool bit point, or cutting edge, to be in line up and down with the follower point. To say it another way you need to have the follower point and the tool point to be the same distance in from the same edge, say side to side not up and down. Up and down is very important also but side to side is too. That way when you apply the tool to the piece and move it back and forth they will be in unison. You will see what I mean when you turn your first piece.
