Completed deburring the aft ribs, they are ready to form.
Jumped to the -08 gussets. I transfered a pattern from the plans to a peice of manilla folder material and used that to draw out the shape and locate the holes on aluminum sheet. I then cut out the gussets with snips, deburred on the scotch-brite wheel and bent the two flages per on the break and a pair of hand seamer pliers.
