Take some bent sticks and some string and make a boat-shaped object.
We're going to take all those sticks and tie them together in the shape of a boat.
The keel and stems are tied to stiff T-shaped jigs to hold them in the proper shape.

The stringers are 3/8" x 3/4", the ribs are green branches from Kiawe (mesquite) trees as thick as I could make them without breaking during the bending process, which is about 1/2" thick.
There are 20 ribs. Each is lashed to the keel in the middle. They are also lashed to 5 stringers and 1 gunwale on each side. That's 13 X 20 = 260 lashings you're going to do. Think of it like knitting. It's going to take some time, even if you could do a lashing each minute. Get a good comfortable work environment and some good books on tape to listen to. Or some friends to talk and help. It goes a lot quicker with more hands. It doesn't make much mess or noise, so you can take your frame with you to any shady/secluded/sociable spot that suits you.

In this photo you can see some of the "bowstrings" that pull some of the ribs into the proper shape.

Step 1: Set up the Wickets

We mark the gunwales with a line every 7.5" to place a rib. Set up all your ribs and eyeball them.
Star trims a rib to proper length with the pullsaw and knife. Each rib has a thick end and a thin end due to the taper of the stick they are made from. That's not a problem. Flip ribs around so thick and thin ends alternate on each side of the boat.

Don't get too carried away with perfection yet. Just eyeball the ribs and make sure they're long enough and not too deformed for your type of reality. We're setting them up just to make sure there are enough of them. You might need to go back to episode 2 to cut and bend some more ribs.
 What are the dimensions of the stringers? Thin enough to bend well and thick enough to be structurally sound?
I used to teach a class on skin on frame boat building, easiest material I found was cheap mahogany door skin. It's about 10 bucks at Home Depot and is good for 20-30 strips (depending on width) after some easy ripping on the table saw
Thanks for asking! thats the sort of info that's important to have in the right spot.<br /> <br /> http://www.instructables.com/id/Outrigger/step5/Rip-the-Gunwales-and-Stringers/ says:<br /> The stringers are 3/8&quot; x 3/4&quot; x 16' which is longer than we really need, but we got lucky with boards. We'll cut them down later when we fit the skin on.<br /> I've updated this step to include the info. I haven't updated my culture to use the Metric System, it will take a long time to undo the damage done by Ronald Reagan, who switched us back into the Imperial System.<br />
&nbsp;Thanks for the update. So one could use a 1x12 clear cedar or pine board (however long) and rip it down to 3/8&quot;strips to use as stringers and ribs? I really would love to build a canoe like this, I recently moved to Oregon and it just seems heretical to live here and not have a canoe. I have access to a very good woodworking shop, I'm thinking I could cut out my strips of cedar or pine, soak or steam them, and manhandle them into a canoe, obviously with a little more finesse than that. My concern is: Is it&nbsp;necessary&nbsp;to use saplings or willow rods (as i have seen many others do) for the ribs? Wouldn't a thin and supple strip of softwood work just as well and have the advantage of perfect consistency?
my cousin built a similar project, i took some pics and threw em on <a rel="nofollow" href="http://www.flickr.com">Flickr</a>. check em out <a rel="nofollow" href="http://www.flickr.com/photos/rossbeane/2804356873/in/photostream/">pic 1</a>, <a rel="nofollow" href="http://www.flickr.com/photos/rossbeane/2804355841/in/photostream/">2</a>, <a rel="nofollow" href="http://www.flickr.com/photos/rossbeane/2804355461/in/photostream/">3</a>.<br/>
Nice! how do you like it? is there more information? I'd love to hear about what did and didn't work for him!
This is a cool instructable but it looks like Star is doing all the work.
