Vans Aircraft RV-12 Build, Section 23 Side Skins (part 4)

Reference: page 23-05; 2.0 hours

This entry is a continuation of installing the mid side skin on to the RV-12 aircraft designed and kitted by Van's Aircraft.

Step 1: Cut out the wing spar penetration in the Fuselage Side Skins to create left and right side skins. Start by marking out the shaded areas labeled in Figure 1 and 2 of the RV-12 plans on page 23-05. Drill a large hole with a unibit inside the shaded area. Use snips to cut close to, but not at the edge of the shaded area. Snip around a final time removing material up to the trim line around the shaded area. Deburr the edges of the hole.
Builder's note: I used a hand nibbler purchased from Aircraft Tool Supply. It's slow going but doesn't distort the aluminum like aviation snips can.

Step 2: Mark the Fuselage Skins left and right.

This completes page 23-05. The rest of the time was spent deburring the edges of the skins.
