    Wayne,
    Thanks for the idea, I'll give it a try. I'm having computer issues and I think I may have to upgrade or compress my photo files.

    Hi Wayne
    If I understand correctly: the rivets (for the outside ribs) do NOT go at the intersection because the spar does NOT intersect the rib flange (only butts up to it) so stick with your original 40 spacing to complete the rib riveting. The rivets for the spar flange are OK as you have them laid out.. in the center of the spar.
    Make sense?

    Now I am comprehending!
    This is a very common situation, so this is good that you are considering it now. Whenever you are laying out rivets, your goal is to evenly space them out between your 2 endpoints. This is where a rivet fan is used, making it quick, easy and accurate. The space between each rivet will not be exactly 40, usually something less... but consistent... or - if you are trying to line up the rivets with another row that is already placed, you can make (as in this case) the last row less than the others (30mm) It is your choice, the idea is that the spacing they ask for in the plans should be the maximum spacing...
    So in this case, if you use a rivet fan for an even spread, I bet the distance between the rivets will be - maybe - 38mm ? But they will be even... OR, if you want them to line up with the end ribs, then do that (40mm), and the spar rivet line will be left where it is... but not at an even 40
    You are all set!
