Hello Don,
This is one more of many I have received from you that I thought was
terrific. Obviously, you are peaning the metal around the screw hole to
make the hole smaller. While I'm not anxious to using the procedure, I
believe it might be easiler to use an automatic center punch around the
hole in the same manner as the screwdriver with less danger of bending
the rail. My guess is the dimples should be around 1 to 2 millimeters
from the edge of the hole. Does this seem reasonable to you?
