Step 11: Dowel the bow and stern
Peg the gunwale ends together using 5/16 inch dowels driven into 19/64 inch holes. Use 6 dowels for the bow and 5 for the stern. Do not put any dowels through the risers. As before, when you dowel, drill and drive one dowel at a time. Resist the temptation to drill all the holes at once.
Drill the first hole closest to the end straight through and make sure you don't get the ends out of alignment when you are drilling.
Drill all other doweling holes through the gunwales at an angle from the horizontal as shown in the photo below.
