Rudder is now under way. Took a while to draw the layout lines from the plans and then scribe a reasonable curve. Bought reading glasses to read the fine print on the plans.
rudder is penciled in and 3/8 ply doubled up. ready for glue.
The dark spot is residual baking soda from a spill earlier in the construction process. Will not be finished clear anyways. High gloss smooth.
Mock up of water bottle and gym weights, glue tomorrow.
ADDENDUM -
The rudder blank was not lying flat enough for my liking, so nailed down the perimeter while the glue sets off. Stay tuned...

The rudder came out fine. I then moved on to the cheeks for the stock. The plans show a trapezoid with only one right angle not coinciding with any of the lines, and a diagonal to show the angles on the trapezoid. After trying to mark this onto the plywood for an hour and a half, I gave up and went to bed. Today, got up and pulled out the Masonite I had used for the centerboard trunk and made a pattern. As lines are easily removed, this took far less time, and cut so well that just a little fairing up with sandpaper has given me a nice pattern to work from. Also discovered a plank of 5.5" mahogany in the garage for the filler blocks.

| rudder stock blank sitting on top of the blade stock. easy to see how these pieces work together. |
 |
| ready for shaping. will trim the little spot in the upper right corner after rudder stock is built. this area controls the pitch of the blade. 7/8 needs to be forward of the stock for balance. |
 |
| rudder cheeks, next is the filler block. and doublers. |
 |
| Whole assembly mock up. |
 |
| Pivot tested. Time to shape blades, and order hardware. |
