Empennage or 'tail feathers'

This is where the day ended, with the HS attached to the fuselage with enough AN3 bolts in place for me to be sure nothing is going to move in the night. The good news is on the digital level. Call me slapdash, but I can accept 1/20th degree of error!

The incidence of the HS is similarly accurate wrt the cockpit rails.






Here is the view from above. You might notice the bolt heads are pretty close back to the web.I will come back to that in a moment.

We spent the whole day on the task because issues of edge distance were quite troubling. It is quite impossible to fully meet all of the rules.




In this picture you can see the outer attach holes are placed slightly inboard of the ideal location on the longeron. The reason for this becomes clear in the next picture.

Another point to notice here is the bolt holes are slightly forward of the centerline on the cross piece.











This picture might be confusing at first. The camera is inside the fuselage pointing vertically up. If the holes in the longeron had been further outboard, they would have been located too near the ends of the cross member. (In retrospect this could perhaps have been made minutely longer, but I am happy all is well.)

One thing none of the pictures show, though the third hints at it, is that the two cross angles to be bolted together, one on the HS the other across the fuse' did not line up vertically above each other. I have re measured every dimension and can see no error. VANS expect any misalignment to result in the upper angle being behind the lower one. In my case it was nearly 1/8" forward. This is the reason for the bolt holes being forward on one cross piece and back on the other.
