Sounds like a good solution, exept don't cut a slot in the dowel. Just plane one side near the ends to make a flat spot. Glue the blade on to that face. This will be stronger and easier than a slot.

Or else get a 2x4 and make a greenland paddle.

: Finding myself in a similar situation, I bought a dowel from the hardware
: store and was thinking about cutting a slot in each end. Then I would
: trace a neighbor's paddle blade onto some left over 1/4" birch and
: cut it accordingly. Put the blade in the slot and glue/screw and I'm done.
: Whaddya think? Any better way?

: BTW, I do plan to spend more time on a paddle when I have more time!
