I am getting ready to brake spars and double checking everything. I have patrol plans # 250. I built my rib form block from drawing 4. The full size template. The main spar height on the full size template measures 8.625 inches. After building the block and forming the ribs they measure aprox 8.7 inches. However, the main spar drawings show this measurment to be only 8.25 inches. Something isnt right. The template very clearly does not match the plans. Has anyone else encounteted this. Suggestions?
