So for this attempt, everything is going to be made out of that scrap redwood that I've been using for practically everything. Why? It's free. I wonder if I can make this whole windvane getup for < $30. I bet I can. If it works, I'll make a sexier version out of aluminum and fiberglass poles.

Anyway, here's the pendulum oar, glue'd up with PL Premium. It's 6 feet long and got a 5-inch chord. It's an inch thick. That will be a pretty chubby foil shape, but that's OK.

I happen to have two dinghy pintles for 1-inch thick rudders, so I'll use them to hang the oar off the oar carrier, which you can see glue'd up and clamped, to the left of the oar.
