Pietenpol-List: wing rib drawing

ChrisThe wing rib pattern from Don P. is not a good pattern. If you loft the ribper the plans you will find there is a big difference in dimensions. Eachtime a pattern is copied the size of the pattern changes, I think this isthe problem. I made my rib jig by lofting per the plan. I then drew thelocations of the drag/anti drag wires on the wing plan, Using theintersection of where each wire passes through the rib, I used a scalemeasurement to determine the distance from the leading and trailing edges tothe wires. I transferred these locations to the full size rib jig. using thepattern and wire locations I was able to determine where exactly to placethe diagonals and uprights. this is a lot of work but I think its worth thetrouble.Garyfrgtdog(at)worldnet.att.net________________________________________________________________________________
