So i'm at the point in the van's practice control surface kit where i need to drill the spar. Now the instructions say to just clamp the A-905 R/L ribs to the ends of the spar amd drill out the rib holes with a 12" drill bit (assuming #40 here for the AN426AD3-3.5).
This seems like not the best way to get a good fit on the skins. So i cleco'd the skins to the ribs and clamped the spar in place. What i want to do is use a normal #40 jober bit to drill the spar using the skin as a guide. Is this a good idea/ better than the instruction or am i missing something?
