The sheer plank is replaced to the sheer marks on the new ribs .
In preparation for the new ribs evenly spaced holes were drilled in
the planking and the copper clout nails set in the holes . As the hot
rib is steamed into the hull it is soft enough to drive and clench the
copper nail through the rib without drilling the oak rib .( that is if
you can get them all nailed in about two minutes , so setting the
nails helps reduce the time fumbling with nails when you're in a hurry
The ribbing completed .
