Section 2: Joining the Wing HalvesParts Needed• Right/left wing panels• Dihedral brace• Plywood wing dowel plate• Wooden dowels• Wing bolt plates• Wing trim tapeTools and Adhesives Needed• 30-minute epoxy• 6-minute epoxy• Mixing stick• Epoxy brush• Masking tape• Hobby knife w/#11 blade• Rubbing alcohol• Paper towels• Wax paper• Ruler• Felt-tipped pen or pencil• Medium sandpaperStep 1. Locate the plywood wing joiner. Using the ruler,determine the center of the wing joiner and mark it with a felttippedpen or pencil.Step 4. Mix approximately 1 ounce of 30-minute epoxy.Note: It is extremely important to use plenty of epoxy whenjoining the wing panels together. It will also be helpfulto use wax paper under the wing center when epoxyingthe wing panels together.Step 5. Using an epoxy brush or a scrap piece of wood, apply agenerous amount of epoxy into the wing dihedral cavity in onewing panel.Step 2. Trial fit the wing joiner into one of the wing panels. Itshould insert smoothly up to the center line marked in Step 1.Now slide the other wing panel onto the wing joiner until thewing panels meet. If the fit is overly tight, it may be necessary tosand the wing joiner.Step 6. Coat one half of the wing joiner with epoxy up to theline marked in Step 1. Install the epoxy-coated side of thedihedral brace into the wing panel cavity up to the markedcenter line.Step 3. The correct dihedral angle for the wing is 0 degrees (atthe center line). Place the wing on a large flat surface one wingpanel resting on the flat surface. The other wing tip should be at1 1 /8'' in height from the surface (see illustration below). Ifnecessary, sand the wing joiner until this is achieved. Thereshould be no gaps in the wing center. Once you are satisfiedwith the fit, remove the wing joiner from the wing panels.0 °Flat Surface1 1 /8''9
