Hi group,
I'm on step 5.
This is the step to machine countersink the fuel tank attach screw holes. Is there a particular reason why this step would follow the riveting of the nutplates? It seems like it could have been done before step 4. I suppose its not that big of a deal, but was concerned about any shavings that might be left over inside the nutplates themselves. I can blow them out.
Further, the instructions nor the illustrations do not say what screw will be going inside the nutplates. This would be helpful in determining the depth of the countersink. Can I presume that the screws that came inside the same bag as the nutplates will be used? (bag 3007).
Finally all the way at step 8 says to prime the areas where countersinking took place, however the nutplates would already be on by this point.
I know there have been revisions to this page, but I believe I am on the latest.
