Chad,
Great build thread. Did you find it necessary to bevel the rudder post ? It would mean cutting out a new post out of 1/2" stock or laminating to the existing 3/8" post. ( No bigge, but gotta watch the weight).
Besides function, I sort a like the appearance of a bevel on the tailpost.
Then its time to start beveling everything.
I mark down the centerline, then use a bit of trig to determine where the bevel should intersect the surface at the root and tip, and then place a strip of tape along that line for a guide. I do most of the beveling with a planer, and a sharp blade and a lot of patience, and only do a very light final sand. The only trick is the hardpoint, I usually bevel around it and then get it close with the belt sander and finally match it with a sanding bar to the rest of the surface.
If you are careful you can get a bevel that is gapless when deflected.
My typical throws for beveling are,
Ailerons - 25 degrees up/down
Elevator - 20 degrees up/down
Rudder - 35 degrees.
I also always double bevel both surface and fixed part, 10 degrees on the fixed part and the makeup on the movable part.
