Hello Kolbers,
Your question is not “silly” Wesley!
The great thing about the Kolb list is that there are no “silly” questions; everyone on the list has a different background and bring a variety of experiences to the list. So ask away!
Two days ago, the North American distributor of Oratex fabric asked me what I was planning on coating my wings frames with before covering them?
My memory is that almost no one treats the aluminum with anything. I do have a recollection of the story of Kolb once coated a frame with Zinc chromate for a fellow who lived on the salt water of Chesapeake bay and intended to operate on floats.
My question for the list how many inspection ports do folks put in their wings?
Thanks,
Nick Cassara

Put as many inspection rings on your wings, or any other place for that matter, that you think you will "ever" need in the future. All you have to do is process the inspection rings during covering and painting. If and when you ever need to get inside, simply cut out the inside of the ring, then place the pre-painted inspection covers on them. john h |

Brother Cassara:
Not sure what the majority of folks do, but I put one ring on each side of the spar at the strut attachment fitting, and one
at the root to look at the drag strut attachment to the wing butt rib. I open and use all three at each annual.
No reason I can see that a man could not put more on the wing if desired. Guess it depends on how pessimistic one
wants to be.
Worth what ye paid fer it…

I don't have a Kolb yet, so I don't quite understand how an inspection ring works. A picture is worth a thousand words.

Brad/Kolbers:
The ring is a plastic reinforcement for the inspection hole covers. Keeps from tearing the fabric. Gives the cover springs something to hold on to keep them in place\.
Here's a bunch of questions and answers about inspection rings:

Google this, "fabric aircraft inspection rings" and hit IMAGES. You'll get a lot of photos of rings and how they are used.
