This is an early version of how I did my stab so I would not have any problems cutting the elevator from the stab. Since the ribs have reference lines for the cuts, I sheeted the elevator up to one line and the stab back to the other line, leaving a gap. We'll see what happens when I cut the sections apart.
The stab is now going to wait for the arrival of the 1/4-inch CF rod to implement Bill's idea. I'll start on the fin and rudder while I wait.
Cheers,
Richard
