Idon't think they meant to have you enlarge the holes. Rick The only place castle nuts are required is where there is a movable joint. I can only be sure, in time, the holes will elongate if the bolts are loose enough to allow movement, unless there is alowance for routine lubircation. Iused locking nuts, and cinched them up with about 30 lbs of torque. The note in the plans has to do with 1020 steel, not 4130. Not sure if that makes a difference, but 4130 certainly has more tensile strength.Chuck G.NX770CG________________________________________________________________________________
