About a year ago, I met another rodbuilder from the back woods of central Idaho. He lived in a little town of less than a 1000 people and only got to town two or three times a year. While he was laid up by an accident one time, he ran across a book that mentioned building bamboo rods. He thought he would try it and fiddled around building his own conception of a planing form and scrounging even garden stakes for material. (They don't work he told me.) Where he saw the idea for the former I don't know, but he built it himself. Just thought that you would like to see how the other half lives.

The apex of the triangle has been filed off to give the taper. The strip is glued to the apex, and the whole thing rotated 1/3 so that the plane rides horizontally
