I have been trolling through a LOT of builders websites and I have noticed that some builders have chosen to jig their empennages. I was wondering if it is truly necessary with the match holed kits and if it would give any noticeable difference in accuracy
The jig is used when drilling the skins to the structure. When you rivet on the jig you have some of the attach points removed so parts don't stay in the structure permanently.
So what that really means is there is no needed for a jig once the holes are drilled or if they come from vans pre-punched.
Pay very close attention to edge-hole-distance when drilling a few pieces on the front spar of the horizontal. I see a lot of people have to redo those parts.
