I know I'm being a worry wart but I would like to get through the first week without ordering replacement parts
I am working on the HS and Vans guide shows using a dimple depth .005 below rivet flush for underlying structures.
When assembling the forward HS spar, there are four countersunk/flush rivets. I counter sunk to .005 but that didn't seem to be enough depth for the spar to sit inside the matching countersink. After some test rivets in some scrap it appeared that .01 would work better as the Spar sits flush with the support Alum angle.
With that out of the way I am now starting to dimple the HS ribs.
Is this perhaps the area where dimple depth should be .005 below flush (when a rivet is inserted into the dimpled rib)? Should the dimpled skin sit flush on the rib when the dimple depth is correct or should it be slightly above before riveting?
