oh man!!
oh man!!
well tonight i either made a small error, and i should move on...or...i made a BIG mistake, and i need to order a new rudder skin.
i need some advise here.
here's what happened...i was happily dimpling along with the pneu squeezer when i made what seems to be a very common mistake. though it's slightly different. i just BARELY missed the hole, and ripped the hole. i didn't make a new hole and i didn't get full pressure on the squeezer by quickly realizing what was happening, and released pressure. after a few choice words, i got to looking at it, and i figured that i'd just lightly tap the metal back to flat, and dimple it to see what it does. here's a couple of pics that may or may not tell you guys anything. the hole in question is the one at the end of the rivet row.
if the picture is clear enough, you can see that the dimple turned out very nice. however, there are a couple of 1/8th inch or less tears coming off of the hole.
if i go with a 426 4- rivet, i can probably get rid of most of the tear. is this feasible here on the trailing edge? should i just go with the callout rivet and move on? should i replace the skin? i hate to do that for such a small tear, but i wonder about cracking down the road.

Chad, I didn't make my -9 rudder yet so please forgive my naivete'.
This edge is normally prosealed, correct?
It also has the wedge sandwiched in between the sheets?
Clubbing up to a -4 wouldn't be out of the question in my mind. Also, just moving on with a -3 should be fine as well, as the area seems to be TREMENDOUSLY overbuilt and the proseal will firm things up as well. A question to Van or your DAR should be your determining factor.
I don't think you will need a new skin. This is going to be a painted flyer and not a polished show-er, isn't it?
If that is tour worst screwup in the entire plane, you have nothing to worry about!
My $0.02, FWIW.

hey jim, did you notice on the plans that it calls for a "slightly beveled" edge on the c-sink skin to rudder skin transition? i think it may be optional, but did you do this? i can't figure out what that means or where they're talking about. is it more specific in the checklist? i haven't read ahead yet.

I did it on my 9. As a matter of fact if you do a search you should get some pictures I believe.
Basically I beveled (sp?) the edge of is so that the transition between the two pieces of sheet was not as noticable.
