I mounted it and drilled it yesterday and when I removed it, much to my horror discovered that the edge distance for the holes varied between 3mm at the top and 5mm at the bottom. Not going to work. Im trying to analyze what happened. It fits tight to the ribs. At first I thought that sliding the skin toward the top of the rudder would help, but I only gain about 2mm by doing that for a uniform 6mm edge distance with careful placement. Perplexed at this point. The part is clearly junk, but I need to figure out what happened before I go after a second attempt. Ill call Zenith on Monday. Maybe the skin is too small? Has anyone else run into this? Does anyone know the max distance along the front face of the spar from the bottom of the spar to the bottom edge of the nose skin. Larry Portouw Ft.

Fortunately, Airparts is only 20 minutes away for me, but I think I may own a couple of bricks in their building before I'm done. One thing I did to assure success (pc term for cheating) was to deliberately cut the skin about half an inch wider, drill & cleco as before on one side, bend it around and backdrill the other side, (thus assuring plenty of edge distance,) and then cut the excess off. ----- Original Message ----- From: Subject: Zenith-List: Rudder Nose Skin- 601XL > --> Zenith-List message posted by: > > Well, Ive just screwed up my rudder nose skin.

Did you drill and cleco the nose skin under the rudderskin first? You are supposed to drill and cleco it on the outside of the rudder skin, then remove it, trim it, then tuck it under for the final installation. Let me know if this helps.

I messed up my rudder's skin too. Although it looked like I was doing well with the oversize skin, when I decided to make the initial rough cut before the final cut of the skin, I cut too far into the rudder and &?%$/ up the skin. I tried to make a final cut to see how it would look like and here is what I saw: http://mthobby.pcperfect.com/ch601/images/p6t52d.jpg So, next day, I made three new ribs (it's hard to duplicate holes in those ribs that are not at top or bottom of the rudder) and a new skin. http://mthobby.pcperfect.com/ch601/images/p6t52f.jpg Of course, during the project, I found a multitude of new ways of making mistake and re-doing some work. In the end, the result is pretty impressive and while it takes longer than I estimated to complete the project, I'm very satisfied of my accomplishment to date. See my picture of the day: http://pages.infinit.net/mthobby/daypict.jpg One thing I learned that really helped me for the project is installing all skins oversize by a couple of inches. Then, they are not cut to plans' dimensions, but rather to fit. My technical advisor (mentor) told me to do it this way. The other thing he told me is "measure twice and cut once"... but this I had a lot of difficulty with. Good night!
