However, Rather than using a deburring tool , I would recommend a scotch brite disk ( blue) on a die grinder. On .016 skins, use a light hand.

I'm not a structural engineer either but I'd fly with it without worry IF I someone at Van's confirmed it was ok. The directions clearly expect you to provide a hole for wiring. I'm not where I can review them but I think they refer to opening an existing tooling hole. It *looks* like your location is ok to me but I'd verify it with someone with more experience and understanding of the problem and that's what Van's is there for. If they have concerns, whether they run the calculations or not, I'd replace the ribs. My guess is, they won't have a problem with your location - and be sure to let us know what you find.

I agree with all he says. As I recall the plans suggest enlarging the forward tooling hole but if you drilled it out large enough for the conduit you would be into the forward flange of the rib. I acually just routed my conduit through the rear lightening wholes already in the rib, cushioned them with a short piece of vinyl tubing and secured them with tie wraps.

I then ordered the 3-flute cutter and also Avery's 6-flute chatterless countersinks. When I used the 3-flute cutter in a B&D cordless screwdriver and looked at the holes under a 10 power glass, I found that the gear resonance from the screwdriver was leaving what looked like tiny gear teeth all around the holes. From then on, I used only the 6-flute countersinks, mostly with a Craftsman (B&D) 2 speed small cordless drill that uses 2 VersaPak batteries. It only needs one battery at a time for slow speed and just a quick touch to each hole is needed for a smooth result. I lengthened one of the 6-flutes with a piece of 1/4 inch rod, a small length of 1/4 inch ID tube and 5 minute epoxy. The 6-flutes also work well for countersinking the occasional flange for nutplate rivets. I hope that your replacement rudder holds up well and I agree that the guys who are taking shortcuts now are just taking a shortcut to trouble later on.

He is working on his elevators. It appears that the directions for the folded trailing edge is to put a "bubble gum" size blob of either RTV or tank sealer on the rear of the stiffners when you close. This bonds the left and right (or top and bottom) skin stiffners where they nest next to each other to reduce the vibration cracks.
