Subject: Pietenpol-List: Rib verticalsRoger: When I built my ribs, I put verticals on both sides of my sparopenings. I made my jig to except 1" wide spars like the plans and therib drawing that came with my plans. I ran into trouble when I orderedmy spars from Western Ac. Sup. The spars are 3/4" wide. now I'm going tohave to put a 1/8 strip of ply at each rib location to to take up theextra 1/4" gap in my rib spar openings. When I built my center section Ifound that the vert. stick on the back side of the rear spar is going tointerfere with my aileron cables, so I had to remove them. If I had itto do over again, I wouldn't put the vertical stick in front of thefront spar or the back side of the rear spar. When I get to my wings I'mgoing to cut those vert. sticks out. I may even save a couple of lbs. ofweight. also If you add the vertical sticks, consider weather or not youare going to use 3/4" wide spars. ( I think 3/4 wide spars are prettymuch the standard these days--cheaper than 1" and they do ok in PittsSpecials doing hard aerobatics.
