When I started out, I ordered 2 sheets (2'x2') of aluminium of every width I would find in my kit. I use those to practice on when I am about to go into 'riveting' mode. It's saved me.

YMMV

Default I'm in Fayetteville

Hey! I am in Fayetteville and I have been co-building a 9a with my aunt (builder of an early rv-6a) and the kit was a project that was purchased (poor build quality). So I have had tons of practice drilling out bad rivets and squeezing in the new ones. Not saying I am a genius but I'm pretty good with a squeezer if you wanted to meet up I would be happy to look it over with you and lend assistance where I can.

You do NOT need to do anything fancy or out of the ordinary and you don't have to order anything expensive. The problem is the part you're trying to squeeze isn't being held down. Don't go spending a much of money on a new squeezer.

On the RV-12 on those rivets you're talking about -- and don't ask me why -- the tendency of the work is to turn as you squeeze, which puts the rivet head out of alignment with your squeezer. That's going to happen every time; ask me how I know.

Squeezing these rivets won't work (or at least it won't work well), unless you clamp down the assembly and then squeeze. Also you want to orient the squeezer so at the beginning of the squeeze you're putting pressure on the shop head (as I recall the parts you describe, I actually had to pull slightly on the squeezer) I can walk you through it.
That may be a lot of it. I have a hard time trying to clamp the work down (I also worry about damaging the work by clamping too hard). I'm also trying to keep pressure on the manufacture head but in the process I know I'm flexing the rib a little.

Clamp it down by the flange on a rib or two. Put a small piece of thin wood (I use those Home Depot shims) on the flange, and clamp it to a -- preferably -- EAA Chapter 1000 workbenches using your typical bar clamp.

This will make all the difference in the world and when you see your perfectly squeezed rivets (you know you've squeezed to the proper diameter when you feel a pain shooting up your arm. ) , you'll kick yourself for not doing it earlier.

I would welcome that opportunity. I have a hard time meeting up with anyone from the local EAA chapter because of my work schedule (I work nights and weekends).

I'm building in my (tiny) dining room at the moment so I don't have room for the EAA table (although I do have the plans). I will have to find someplace bigger when I start the tail cone as it won't fit out my door! I've been thinking about my bigger (but still rather small) two car garage but I need to find a place for my motorcycle and car first. I'm also on the waiting list at the airport but it's a long list.

All that said i will clamp as advised when the new parts arrive!

I made the forward fuselage cover on my RV4 5 times. Granted, the holes had already been drilled in the structure underneath and dimpled by the previous owner of the project, so I was not match drilling. Picking up on dimpled holes on a curved piece is tricky.

The rear fuse skin took 3 tries, at $85 a try. And I am still not happy with it. I might do it again.

In the end I have used almost all the scrapped aluminum for various other parts - baffles, interior parts etc. And various airport scroungers have made off with the rest of it. So it all worked out. Certainly you need to get some help with your technique. Then it will be much more fun and satisfying. It is tough learning on your own.

You need to be a stubborn #$% to build one of these. You will get way better at riveting. The size of your scrap pile will probably depend on how much help you get to avoid the usual pitfalls. Relearning all those lessons can be time consuming.

Default Come see us at TruTrak (KASG)

If you ever need a flying break...

We would gladly give you a motivation ride in our company RV-10 (we used to have a 12, but no longer own that aircraft...or I would offer it).

Come see us, let's have a beer and talk about airplanes.

Jim has that 12 now, doesn't he? I've seen it at the 732 Chapter meetings (those few I'm actually able to make). Thank you, I will take you up on that as soon as my schedule allows!

Eric,
Nice to meet you, thanks for showing us around. My Lil Guy enjoyed the hangar flying! Sorry I couldn't offer a ride this time, remember as long as the work is airworthy most of the cosmetic mistakes made are long forgotten and become pretty minor after it's flying. Yes, it's so worth it!
