I'm finishing up the aft bulkhead... ready to drill a clearance hole in the bottom skin for the tail tie down ring, but I'm not sure what size hole to drill. The manual says 5/8". But the diameter of the "stem" of the tie down rings from Van's is bigger than 5/8". Is the intention that the tie down ring will bottom out against the skin? Or should it clear through the skin and bottom out against the extruded block?
Likewise, the holes in the wing skins for the tie down rings are only approx 3/8" on my QB wings. So here again, the tie down rings would bottom out against the skin.
In both cases there's a gap between the skin the extruded block, so screwing in the tie down ring would tend to bend in the skin. That doesn't seem right.
Those who have been here before, please impart your wisdom!
