Sorry! Maybe a mental exercise. I can't wait to hear John's (0.02) about this one. The size of the rivets in the thin skin is perhaps the biggest issue. After that, if using 470 rivets with the manufactured head sticking out of only one side, each one should have been reversed in direction to counteract the air deflection off the proud manufactured heads. There are several older planes that have rivets the size of marbles sticking out of their skins, but not an RV. I guess you could use the rudder as a drag/dive brake. With that said, chock it up to experience, practice and do it again, it will only come out better each time you do it over. You got to set a high standard from the start. It is kinda fun anyway.

Here is the deal the way I see it. If you are not the designer or a aeronautical engineer why would you change the recipe? All this stuff(DOUBTS) we do not have a definitive answer. YOu are only a test pilot to some degree, as other have mostly the same plane, but yours now with the modification will be different, so you can throw away the test flights of all others and all the experience of other who continue to fly. So when you are flying your new RV 10 and hopefully you are in tuned to what you hear and what you feel, your plane sounds different or feels different...what will your mind do. Hopefully it will try to figure out what is going on. Now add on all the little steps you skipped, the directions you did not follow, the things you could have done better. Now add all those things into you figuring. Overload, worse, you freeze. You make a bad decision or you put it down in an unfriendly area or make a bad landing because you are overwhelmed. This is a no brainer. Minimize the potential conflicts. JG.

You can drill out each rivet perfectly, but the thin skin has expanded around the oversize rivets..it took more energy to crush them. You guys are really worrying me. WE had an accident sometime ago in the gliding community. It dealt with a pilot losing elevator control. It turned out that the tape holding the mylar gap seal had peeled up and caused the airflow to seperate enough so that the air did not come back down on the elevator, rendering it ineffective. We fly with parachuttes, but he wasn't high enough to use it. That is how a simple issue can have huge implications. This doesn't seem simple to me. This is troubling...you guys are flying over my house. I need to first get a TFR over my home and then go for a permanent flight restriction. Maybe a concrete dome embrella. And I was wondering whether this was a joke. Call Van's but talk to a designer not builders support.

Not something I like in the back of my mind when I go flying, whether a minor issue or major issue it's all cumulative in the end. JG's point, "I forgot the issue of them being countersunk holes with non matching rivets.

This is the best advice from all of us, but do call Van's. I'm sure they'll give the standard "just move on" statement. I suspect, as Ron is implying, that when you are whipping out the parts towards the end, the rudder will look dead simple and you'll come back to it knowing what you want. I know that I'll rebuild my VS since I now know so much more about building, am much more skilled and can see doing that piece over two or three long days, instead of the month it took me at first. The rudder is a little more complex, but it might beat getting RV-10 builder snickers at OSH. Or, you could turn it into the latest speed mod. You know, reverse dimples in golf balls!

Jeff, I don't see the #4 rivet size as being a problem, however, the universal head in a countersunk hole is a problem. It reduces the bearing area to practically nothing as the rivet can't fill the countersunk hole. I suggest drilling out the holes. If the results don't look good than order new parts.

I received mine a few weeks ago and have used it to remove only a handful of rivets so far. Although fairly pricey @ $75, I reckon it's invaluable. Builders starting out will find setting 1/8" universal head rivets hard enough, removing them without enlarging or totally destroying the hole can be even harder. This tool perfectly centres the drill bit and sets the correct drill depth, the head snaps off easily, and with a little backing support the rivet shank drives out with a punch. The result is a hole that is as good as the original, enlarged only by the expansion of the rivet when first set. If you have a large number of universal head rivets to remove, like perhaps on your trailing edge, or frequently remove dud uni head rivets, this tool is a godsend. cheers, Ron -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com]On Behalf Of Jeff Dalton Sent: Wednesday, 1 March 2006 4:40 AM Subject: Re: RV10-List: re: I have a Friend who screwed up his rudder - what would you I have some oops rivets.

In other words, the holes are already drilled out with a #30 bit." I haven't crossed this bridge yet, but what about the OOPS rivets? Countersunk head, #30 shaft, a possibility? Maybe the drilled out hole would be too big, but it might be worth trying it on one rivet to see how it looks. My one question: are the countersinks for #30 as well?

As yet us 'southerners' on Oz haven't received the doubler. I have read the AD and am a little concerned about match drilling the doubler into the rear spar from the inside, most likely using the 90 degree drill, bearing in mind that the top rib will still be partly fixed in place. Your experience would be appreciated please.

Wright" Subject: RV10-List: elevator trim tab hardware After fitting my clevis pins to the trim tab horns, I noticed that I'll not be able to get all three washers on that the plans call for and still insert the cotter pin. I figure that should be okay, as there'll be no play in the system. Reason why I'm asking instead of just going ahead is that Van's has been pretty good at stating Maximum or Minimum of ## washers if you're allowed wiggle room. Any one handy to their airplane that's seen this and has a fix? Of course I could be reading the plans wrong, but I see them as stating that all the washers go outside the horn tabs. I have no pic yet.

"It's OK to make mistakes, that's a normal part of building, It's not a normal part of building to disregard it and not correct them". As you progress through this process you will make mistakes, in order to offset that knot that occurs in your stomach when you do screw something up you need to untie the knot by backing up and fixing your mistake I.A.W. the plans/designer/expert intentions. When I first read this post this morning I thought it was a joke as well. My first knee jerk response was to advice your "friend" to call Cirrus and arrange for a demo flight and reconsider building...that was a mean spirited thought :) My advice? Rebuild the rudder, but wait a few in a few months. You won't drill out all those rivets without rounding out too many the holes in the ribs, skins and trailing edge. Attend an EAA meeting and bring the rudder for show and tell. It will make you feel a lot better after everyone tells you that's nuthin....you should see what I did once... Rick S. 40185 Finishing
