Build a Greenland kayak part 6

Step 19 Make a cockpit coaming bending form

You won't need the cockpit coaming until the end of the skin sewing session, but it's a good idea to start it ahead of time.
The bending form should be an oval hoop of 3/4 inch plywood. The rim of the hoop should be 2-1/2 inches wide.
Length of the form should be the distance between deck beams 6 and 7 plus 1 inch. The width of the form should be somewhere between the width of your hips plus 1 inch and the width of the kayak minus 2 inches. For a kayak with a 21 inch beam, 16 to 18 inches is a good width for the coaming
