I assume Bryan was insalling one of these southcos that are just as easy to operate and also dont require tools.

I used a Southco that does require a tool ... same tool I use for opening my cowling doors on pre-flight & checking my Mogas for Ethanol. It is also used to to sample fuel from my (still installed) gascolater. Looks like this:

I found a Hartwell on eBay for $20 shipped. But, it looks heavy and is expensive compared to a Southco. I am leaning towards the wingnut style for the fuel door.

Bryan,

More often than not, I apply the smart-not-hard approach...
Slightly outside the box here, but how about a new door instead of moving the hole to be under the existing one?

Cosmetically, maybe there would then be a bit a asymmetry that might drive you crazy with a new door, and/or only a handful of folks besides AirVenture judges will notice. Probably an internal tolerance level thing - judging by how much time you have invested in polishing, I'm betting you'll move the hole.

Not quite 2 cents there - good luck.

Sean,
Adam and I were discussing a new door. One of the possibilities.

Adam made a new door. People aren't symmetrical either! Still looks ok.

Here is our front Southco setup:

A shot from inside. We used metal rather than fiberglass.

Didn't get to work on the airplane last week. I was in Austin, Texas at National Instruments for LabVIEW training. While I was gone the golf cart blew up slightly.

Looking good Bryan. Hope your "cruising" the neighborhood series isn't affected too terribly!

Here is our new portable jack. It has wheels and disassembles for easy storage in the back of the Waiex. Not sure what all the jacking fuss was about.
Image

In the 3 point attitude the plate was 8 degrees nose down and the airplane was 9.5 degrees nose up. So, our hole pattern needed to rotate 17.5 degrees. We used this simple setup.
Image

Afterwards we will cut out the red line and have a new template.

We found some primed 7075 in the scrap bin. Adam has drilled the holes and is marking the cut lines.
Image

Here is a view of them mounted. They look much better.

To drill the pilot holes in the wheel pants, we made this tool. It is a box with two holes across from each other, 11" back, and 2.5" high per the plans. A 2 by 6 is the perfect width.
Image

Here is the tool in action. Any local Sonex builders, you want to borrow this.
Image

We went a little oversize on the holesaw - 2" rather than the 1.75" called for in the plans. Lets us miss the caliper bolts with no drama.
Image

Here Adam is cutting out the slot.
Image

I cut the first axle. Spark city!
Image

Adam cut the second one.
