How does the upper wing spar brackets pass through the inside rib that is beefed up with plywood? Maybe I am having a brainfart moment! I can't figure how this will work without cutting into the reinforced rib.

Quoted from 509 How does the upper wing spar brackets pass through the inside rib that is beefed up with plywood? Maybe I am having a brainfart moment! I can't figure how this will work without cutting into the reinforced rib.

I found these picture's from a builder on the Legal Eagle forum. I think these pic's will give some idea.

That gave me a belly laugh dick! Have hammer and saw, will travel. Oh your serious!  

You need to make a mod to both root rib and the the one next to it. A cut out needs to be made for these 2 ribs in both wings ( 4 ribs total ) so that the wing-attach straps and the 1/8 ply gusset on front and rear spar can pass through.  ( I too had to make this mod as the rib  set in the project I purchased did not have these cut-outs.)

But it is doable. I used a small rotary cutter for making the slots in root rib which was already glued to the 1/8 ply without the slots.  Some pics below:
