I know this has been covered here, but I can't seem to find a definitive answer in the archives. I have a -6 in need of a new rudder. The aircraft was built ~1995 before prepunched parts were available. The original builder built a new rudder in 1998, when I understand prepunched parts were
available, but I have the receipt from his order and he chose to reorder the same parts as used on the original build: R-402 spar, R-403 top rib, R-404 bottom rib, R-401 skin, 4-406, r-407, etc.
I know I will need to match drill the rod end bearing holes, so that will require at least a R-402 spar.
My question is... should/can I use R-601PP/R-601PP-020 prepunched skin, R-606PP+R-607PP Reinf Plates, R-405PD Predrilled rudder horn, and R-410PP rib horn, or should I stick with all of the old, non-prepunched parts? As a non-builder I have no jigs, and my primary goal with using the PP parts is to avoid the need for one. Is that even possible using the R-402 spar?
This thread has some additional info, but lacks the definite answer I'm looking for: http://www.vansairforce.com/communit...ad.php?t=78729
