All the pieces of the rudder were made so a dry test assembly was in order.
Here is what it looked like.
That looked good, so I went ahead with gluing it all together. As here.
The spring clamps held the sides in place except where they made the transition from a full width to a narrow trailing edge. A G cramp was required there to hold the sides down to the blocking.
As suggested in the build manual, I drilled a hole through the trailing edge and used a piece of wire to stop the blocking sliding inside the rudder. Here it is.
We are getting there!
