Brief Description: Prepped top corner skins
|
|
After clecoing in the tail cone side skins, I started prepping the top corner skins.That means drilling every hole out to a #30 with a reamer (I'm sorry, Van's, I've too much respect for aluminum to abuse it by trying to jam in LP-4 pop rivets into the holes you provide), then deburred every hole and then deburred the edges.
This is another area where I'm concerned for the quality of RV-12s. When Van's uses step-by-step instructions, sometimes it mentions deburring, sometimes it doesn't. Having built an RV-7A, I know that EVERYTHING needs to be deburred. But their instructions and picking and choosing when to mention deburring carries the implicit message to newbie builders that if deburring isn't mentioned, deburring isn't necessary.
This is simply wrong and I wonder how many RV-12s are flying with stress risers all over the place by builders who primed everything figuring that's needed for resale value (a myth) while ignoring the need to deburr.
On that score, I noticed that these two skins -- I think they're F-1279, but don't quote me -- were not included in the tailcone step #1 instructions to roll the edges of some of the skin pieces because of lap joints. Again, that implies these edges don't need to be rolled, and that's wrong, too. They do. There's a lap joint with the side skin.
