Mike Hoover and Bill Repucci gave me some great help earlier in this step, but I forgot to ask this question...
Any suggestions for how to address the F996 fuel tank attach reinforcement angle's use of 3/16" countersunk bolts where they attach to the longerons.
Would it be best to dimple the outside skin for the bolt and then countersink the longeron under it? Do I need some sort of larger dimple die? (I think I had to do this on the rudder counterweight but, if I remember correctly, I used a #8 dimple--because that's the largest I had--for the skin and then I countersunk the lead a little deeper allowing the 3/16 bolt to suck the skin into the countersink.) It turned out good on the rudder, but is this the approach here at the tank/fuselage intersection?
Regardless, it seems like I need to take this step now before riveting things together, but the instructions are very vague at this point.
Thanks.
