Well......yesterday, right after I asked the question, I looked to see if anyone had responded. I saw what Art had said, and I went ahead and pinned through the main spar (balsa and skkkkiiiinnnnnyy). This seemed to work pretty well. But, if everyone now agrees that pinning around the part is probably a better idea, then I will definitely try this way too.

Thank you to all the "pro" builders that answered to this.

I appreciate the help.
