Dimpling Gone Bad

Kyleag04 · #1 08-12-2008, 06:08 PM

Well, I thought I was doing well, getting through the VS and HS without any major missteps. However, today was a totally different kind of day. For some reason, I must have started thinking that the dimpler was a hole puncher!! Not once, but twice did I slip and double dimple my Rudder skins. Now I'm not sure what to do and I am hoping that some of you out there may have the answers to my dilemmas.

First of all, when I was dimpling the rudder spar attachment holes on the lower end of one skin, I slipped and the dimpler put another hole and dimple about 1.5-2.0 diameters forward of the spar attach hole. I'm not too worried about the structural aspects of this hole because it is just in the leading edge portion of the skin, but I am worried about how to hide it. What can I do? Fill it with a rivet after I roll the skins? Fill it with Proseal and paint over it? Any ideas?

My second issue is what I think I've heard referred to as a figure eight dimple. See the picture below. This happened in about the center hole of the 4th (from the bottom) stiffener hole. How can I fix this? Or do I need to order a new skin?

Oh, and this is my first time trying to post pictures, so I hope it works. If it doesn't I'll try something else. In advance, thank all of you for your help.

Kyle,

Welcome to the extra hole club! I challenge you to find an RV out there that doesn't have at least one extra "dimple" hole and one figure 8 hole. This is not a big deal. The extra hole can be filled in and painted over later. As for the figure 8, just clean it up as best you can and dimple, and maybe put another rivet in next to it to make up the strength.

If anyone asks, just say that they are additional lightening holes.

Both of these are like the "secret handshake" for RV builders. You're in the club. Welcome.

When this happened to me it indicated time to go to bed. Dont worry about it, all part of that education and recreation clause in the experimental class.

When this happened to me, some wise guy on this forum (Jeff Point?)

told me if anyone notices it when the plane is completed to ask them words to the effect, "Didn't you get the emergency AD to do this to your plane?" Plug on...

Plug it with a rivet, like I did...once...ok, maybe twice...but not more than three times...I think.

I did the same thing, punching an extra hole. I used two flush sets on my squeezer to flatten it out, then drilled it and deburred. Hopefully it will live it's live undetected.

after you drill it out and put a rivet in it or use the flat inserts for your dimpler or after you drill it out and fill it.....no one but you will know after it is painted.

If it is not 2 holes connected together, I would drill it, dimple it, and rivet it.
