RE: Anderson Kingfisher
Setting wing dihedral is easy. Put 1-1/4" block under wing tip and make the first (1/8" ply) rib vertical to building board, with a rightangled square. fit the joiner tubes horizontal to board, you will need to use a round file on the ribs 2 & 3 to get the tubes horizontal (use a long bar inside the tubes for accuracy) But DO NOT epoxy the tubes in yet! When you have made the centre section, complete with tubes, put it on the board weighted down (housebrick is good!). Then line up the two wings, fit the tubes and joining rods,and when all is square and looking good, epoxy the wing tubes in. Fit loose liteply doublers to tubes when assembling, then finally epoxy the doublers to the ribs - job done!!
