Ray your fix is perfect if buying a new tube, its what I wanted to do, the rib does not need to be replaced if the tube reaches the spar. My tube cost nothing it was the remains of an old plane, it is a little to short to reach the spar but was very workable. I think between your photos and mine others have a good solution to the problem , thanks for the photos. You are correct , new shear webs with grain in any direction is a wast of time, the spar is plenty strong.
