Wind Skin Lap Joint (Inbrd/Outbrd)
Hello! I did ask this on the FB group, so anyone who answered, please feel free to ignore this question! (And thanks for your answer as well!).
The plans have us sand down the forward corner of the Inboard and Outboard wing skins where they overlap. This is to make the part that overlaps the same thickness as the fuel tank skins.
In order to do this, you really need to take off quite a bit of material.
I am not keen on doing this as I'm worried about future cracks. I have seen at least one place on here where a crack developed on a QB wing around a rivet.
An alternative is not doing any sanding and having a 2 inch area of skin 0.025inches above the fuel tank skin.
Normally having the skin drop away (fwd to aft), vs having it stick up is worse from an airflow separation standpoint - but I don't want to pretend I'd have any quantitative data to back this up.
So my question is: Have any of you forgone this step? Or have any of you sanded significantly less than the plans asked? If yes to either of the above, have you seen any issues with stall speeds/characteristics or if you got caught where you shouldn't be ... icing.
Thanks a bunch in advance!
