And I'm supposed to know this how?

From Caleb:

Hi Lee,
A doubler, such as this, is the proper way to repair ovalled holes. That is one of the reasons for having the part installed at all. When you mess up a hole and its ovalled, ...

perhaps a little more data is in order:

I've attached a picture from from the latest set of upgrade drawings dated 25 Jan 2010. I've highlighted the rivets in question.

Folks,

I feel like I'm a little thick sometimes. I have the center spar mostly assembled and I have both the front and back in position for drilling up through the top doubler (6-zu-2-1) However if ...

I think I'll just order a new one from ZAC. That will be safer.

I've been working my way through the upgrade of the center spar and I may have made a boo-boo that may make me build another 6-zu-2-1.

I overlayed 6-zu-2-1 over 6w4-1 and back drilled through 6w4-1 ...

Who knew you had to be a machinist to install the upgrade!

I'm learning about all sorts of new things: transfer punches, reamers,
solid rivets.

The plans state that the main spar attach bolt ho ...

I have all almost all the subkits for my XL. I have the gear kit and the canopy on order (should be here soon).

I'm working on the cabin floor and I just to the the point where I'm going to fit the ...

I've run into this on a few of my pieces so far and I'm at a bit of a
loss to know what/how to fix it.

Here's the story (I'm building an XL):

I am working on the rear fuselage sides and I got t ...

Awesome I found it there.

One more question, kind of nit picking now I suppose.

The bottom hole says "8 mm from the bottom bend". I basically laid a straightedge on the front spar and ...

Folks,

Perhaps I'm being particularly thick today but I could use a hand. I am starting on the elevator horns and something appears to be amiss. I haven't cut any metal yet so I'm safe, but I can ...

I talked to WW about this at Arlington last year. To paraphrase, he didn't think it was a good idea to remove it if you already had your crank balanced. It's balanced against the wobble of the eccent ...

Folks,

I'm having some issues getting the top of the skin on for my horizontal stabilizer.

I've checked that my table is flat and level and the 2x4" supports under the nose is also flat.
...

At one point I posted about borrowing a set from someone.

I planned to make a set of dies or have a set made, but the cheapest price I was quoted was like $500 or some such. I decided to just use ...

I try my best to never speculate when it comes to these kinds of things. Having very little flight experience I have little to draw on to even try to draw any conclusions.

Here is what I know: He g ...

I went to the crash site and took a few pictures with my cell phone camera.

It was an Corvair powered XL. I have spent many an hour in his hanger chatting him up about it. The last time I talked ...

Finally, although it isn't explicitly stated anywhere that I can find, I would assume that the left wing is a mirror of the right?

Is this also true? The flanges of 6w6-1 on the right wing is ...

Folken,

I have been reviewing the drawings and the websites of everyone that I can find that have come before me, and I feel I'm missing something.

Looking at drawing 6-w-00 it gives the basic l ...
