Have any of you ever used one of these to reverse engineer parts of canoes? I’m currently working on a hybrid of a couple of my boats and I think this tool could be useful.

Tex, I just discovered your post. I have not used this tool and had no idea it existed. I hope things are going well with your project.

Perhaps this discussion on the WoodenBoat forum will provide some ideas. Boatbuilders have for centuries been devising low tech methods for laying out complex curves. http://forum.woodenboat.com/showthread.php?258890-Questions-on-taking-lines-from-an-existing-hull

Here is a video with a good explanation of the "tick stick" or "Joggle stick" method. Sorry about the annoying sound track.

Use a flexible batten of clear lumber or plastic to connect the points and draw your curve.
