I'm building an 'extra' slow build RV-6A (the 'extra' is because this kit has no prepunched parts).
The wing skins to be dimpled are all drilled with a #41 (per the manual). I noticed that none of the current builders tools kits (Avery included) include a #41 bit as part of the kit only #40. I am assuming that these kits are centered around the new pre-punched aircraft.
Qustion: has the builders manual changed to recommend a #40 bit? If so, any idea why? Dimpling a #40 hold will oversize it and AD3 rivets will fit pretty loose. Are the skins thicker on the newer models? Just wondering if something changed, or the tool kits are just off the mark...
