Question: Stage 1 of my C210X Manual for the J3 Cub and L4 Grasshopper shows a notch in both wing roots but does not show me when to install the small leading edge dowel. What should I do?
Answer: Your version of the Manual is missing Step 1G and its accompanying picture. After you have completed Step 1F, please do the following:
- Locate the leading edge dowel in the Wing Parts Bag. The dowel is made of wood and is about 5/8 in [16 mm] in length.
- Wait for the 30 minute epoxy you applied earlier to dry.
- Trial fit the wing halves together.
- Carefully insert the dowel into the pre-drilled hole (formed by the channels in each wing root) in the leading edge.
- Mark the dowel where it meets the leading edge of the wing when the dowel is about half way inserted.
- Remove the dowel and separate the wings.
- Carefully position the dowel into the pre-drilled channel in one wing half.
- Position the dowel consistent with the reference mark you made earlier.
- Secure the dowel into place with a small amount of medium thick CA+ such as Pacer Zap-A-Gap.
- Make sure the dowel is reasonably straight (perpendicular to the leading edge).
- Let the CA+ dry.
- From this point on you can proceed with Stage 2 where you apply 30 minute epoxy to the wing roots, spar joiner etc and mate the wing halves.
- When doing so make sure you apply 30 minute epoxy into the visible portion of the dowel channels and over the dowel itself prior to mating the wings.
