Have not had any countersink questions until now. I've read the other threads and I'm still not sure the spar channel and doubler are mating correctly.
I followed the suggestion of countersinking the doubler until a test rivet shows just a small ring of aluminum around the rivet head. When test fitting the parts, I can still see the spar channel sitting just a bit proud. The parts are not flat.
I don't want to countersink too deep. Should I just keep notching the countersink down a few steps at a time until they are fairly flat together.
The test rivet seems to be sitting the recommended .005 or more below flush. I'm way beyond Vans suggestion of just a few clicks deeper than flush.
