: 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.

Hi Shawn

Looks good, but, I was wondering if you got any seperation between pieces, after the glue/resin was applied, clamped and then twisted. Would there be any type of pre-stress applied in twisting the wood strips, and would it be enough to cause any harm down the road.......stream?? Just curious! Looks like an excellent proceedure and will be interested in seeing the completed paddle. Say, do you ever spend ANY time with the little mrs. ?? LOL
