RV-3/4 builders: anyone remember what spacing they used on the screws that
hold the top forward fuselage cowl skin to the main longerons? RV-3 and -4
plans both call for 2.5" spacing yet when I scrutinize pictures I have of
finished planes it looks like many builder's used tighter spacing. Tighter
space could yield increased buckling with the #8 screw dimples.

Randy,
I used 2 inch spacing and it looks real good. I also did things a little non-standard on the forward-most screws (the ones that go through the weldments). It seemed impossible to properly use nutplates here, so I just tapped the steel weldments themselves. I'll probably use a bit of loctite during final assembly.
