This afternoon I started the next step in the rudder construction by preparing the inboard ribs for both the left and right side of the horizontal stab. It is still taking a while for me to read and understand the plans, so after much reading and re-reading I finally understood how to create the notches for the nose ribs. I used the suggested measurements as a rough guide and then used the spars to compare. This worked out OK, but as most people, the edge distance is very close.
