: After reading the WoodenBoat article on the Bird's Mouth Technique for making
: hollow spars, I thought, "Hey, that could be used for paddle
: shafts".

: The magic of the bird's mouth technique is that the pieces are all
: self-aligning and no special jigs or fixtures are needed.

: So, last night, I laid up my first one.

: I used 6 strips of 1/4" x 7/16" spruce, and 2 strips of 1/4" x
: 11/16" spruce (to make it oval). One narrow edge of each strip had a
: 45* rabbet cut in it to receive the corner of the adjacent piece.

: Notice that I increased my strip sizes from those shown to give me an overall
: paddle shaft size of about 1 1/8" x 1 3/8". The sizes shown are
: for a shaft sized for my wife, which I'll lay up tonight.

: I used 8 SS hose clamps and a generous assortment of spring clamps to hold it
: all together. When it was all clamped (ends tightly clamped, middle
: loosely clamped) I grabbed the ends where you'd place your hands with
: screw clamps and twisted a 65* or so right feather into the shaft. Voila!
: A hollow, feathered shaft. I just need to figure out a nice way to plug
: the ends where they're exposed at the blades.

: I also plan to lay up a few straight shafts to build Greenland paddles or
: take-apart paddles.

: Shawn

very nice. make that composite core and you're all set to decrease the thickness of the wood and increase stiffness.
