RE: How to repair wing dowel loose
Well it is going to depend some on your building skills. I'm assuming you are rather new at this so excuse me if some of what I say seems common knowledge. That front part is called the leading edge and if it's split then you will need to glue it all together again. I would recommend that you cut and peel the covering back for a better look and access to the damage. If the dowel is not broken off then simply gluing all the pieces back together will suffice then you can patch the covering or reiron it down again. Depending on how the breack is I like to fit all the pieces together and then soak it in thin CA glue. Some times if the broken parts are just split it is hard to get epoxy into all the cracks, so CA works better. Open it up some more and take some pics and post them so we can get a better idea whats going on.
