Thanks Dave and Jake! We are getting there.

Edit: my iphone must think we are done. See routing options it gave me for the return from Detroit:

About the same performance as autocorrect.

There are 3 holes on the bottom that get drilled through a lot of stuff- splice plate, shim, channel, and bottom tailcone skin. Now that those holes are all drilled to #30, I need the same 3 holes in the cockpit floor skin. Started with a piece of scrap and transferred the 3 holes from the shim to the scrap. I clecoed the scrap to all that stackup I mentioned. Then I picked up 3 holes along the longeron by drilling up from underneath.


Now I put the front skin down and put the tool over the top:


Then I transfer the holes:


On the dents thread, I hope nobody thought I was serious about grand champion. Means a lot more to me to build it with my kid. Plus this thread is mostly trick photography.

Forward tunnel zee clecoed in:

Anybody else see this? Inquiry into Kerry.

Regarding that prior picture, I am thinking a tapered shim for the gap between the angle and tunnel at the bottom. They will mate flush below the hole, but there is a gap closer to the floor. This would make the tunnel narrower here, but is there any spar in that part of the tunnel?

Hi Bryan,

Looks like you just need to tweak the F14 angle a little more in the bottom corner?

Should be easy to do with an adjustable spanner and the spar tunnel removed.

Not sure what you're talking about re the tunnel being narrow but there is no spar in the lower portion when assembled.

Regards
Tony

Thanks for the reply Tony. Sonex tech support suggested checking the angle as well. I put a straight edge across the two front angles and they seem pretty darn coplanar.

So, if I cleco my forward zee to the forward wing mount angles, leave the floor unclecoed, and use a fine tip sharpie through the floor hole this is what I get:


True on both sides.

Bryan, how is the fitment of the aft tunnel zee if you test its position relative to the floor pilot holes and aft wing attach angles?

If you cleco the forward zee to the forward angles, and cleco the forward zee to the floor near the center, do you end up with a bow in the forward zee as you look through the spar tunnel?
