A bit confused here.

The balance tab on the leading edge of the elev is 1/2" wide. Instructions (Step #9) say to cut root cap strips for the balance tab from leftover 3/32" balsa. The only 3/32" I have is either 1/4" or 3/8" wide, none is 1/2" wide. Does this mean that in order to make this cap, I have to glue two of the 1/4" strips together to make one 1/2" wide? Or is it supposed to just be 3/8" wide, thereby NOT being as wide as the balance tab is OR is it 3/4" wide so there is a "rib" at that point too?

The same thing applies for the root end doubler caps (Step #10). the root end of the elev is (1/4+1/4+3/32-a rib thickness) or 19/32" wide. Again do I butt glue 2 pieces together to make up the whole width or is the cap flush with the root or what?
