 Posted: Sun Feb 08, 2009 2:04 am Post subject: Spar cap rivet edge distance |
 |
|
I am trying to drill the bottom skin on the LH wing.
Top went fine and all is jigged ok.
Th bottom skin at the inboard end is fine but nearer the outer end the distance from front to back spar is a little shorter than the pre drilled skin.
This means I have 2,5mm over hang on the trailing edge and the front edge distance is tight to the bend radius.
What is the minimum rivet to the bend radius thats OK ?
I cant see how this dimension can be changed as the ribs are as supplied and the skin drilled on both the front and back , if only it was blank at the front I could get it spot on.
I am puzzled and worried about this.

Kev,
I also found the holes on the lower spar cap were close to the bend radius at the outboard end of the wing. I only found out after I had pilot drilled it! You may find, like I did, there is low edge distance on the rib lower flange where the rib flange joggles over the spar cap.

Kev-
Two possibilities.
1. Your vertical shims moved while riveting the top skin, inducing an
axial twist in the wing. Duplicate the plans set-up and see if there are any
gaps in the shim contact points. If you have gaps the easiest thing to do is
to make new skins from sheet stock. Not the cheapest or least time
consuming, but easiest in the long run.
2. Measure the pre-drilled holes for the ribs along the spar and make
sure they're plus/minus 2mm.
I've experienced both, some my fault, some Zenith's. My best advice is
to nail the skeleton down while attatching the skins. Picture attached.
