Prep work on rudder stiffeners and skin: 6.3 hours

Finished trimming all 16 rudder stiffeners. I used the scotch brite wheel to do the final shaping and smooth all edges on the stiffeners. Following this I checked the fit of the stiffeners to make sure they had proper spacing with the other rudder parts.

 

Right skin, stiffeners, spar and trailing edge.
 

After this I match drilled the stiffeners with the skins and then deburred all the holes.

 

Match drilling complete.
 

I also got all the stiffeners dimpled then scuffed, cleaned and primed them.
