I have a question for those of you who are putting witness holes in the ends of your push tubes. I'm curious to know 3 things.
1) What size is the hole?
2) How do you check it? Visually or with a probe that's poked through the hole? - Is there enough light to actually see something in there?
3) What was your criteria for locating them?
I think witness holes are a great thing and I wish I had thought of putting them in earlier. Now I've got a few to pull out of the airframe if I want to check all of them.
Thanks,
Phil
