This is my first post. I am building an RV-10 and I started the wings (left) about a week ago. I think I have read everything about the wing rib holes for conduits and pressure tubes and I am still confused. Can you use any 1/4" OD tubing? Clear flexible plastic or opaque stiff plastic or lastly aluminum? Can you use tubing purchased at Home Depot or Lowes? Do you always need hard plastic snap bushings or can you use rubber grommets? Now about the holes; I need 2 tubing holes since I am putting in an AOA system. Can I just add another 7/16 hole for another SB437-4 snap bushing, about 1 inch below and aft of the factory hole, as marked in the photo. For the conduit, can I just enlarge the hole shown in the photo to 3/4" to allow for the ribbed conduit even though it will infringe on the stamped stiffener? There is so much written, but so many photos are no longer available through their links. here are my 2 photos.
