Thank you everyone for all the information on the post!
The wood is Alder. The fastener system is the pocket hole system (Kreg).
The fastener system is indeed a problem here! I used the pocket hole system because I couldn't figure out how to clamp the face frame. Even with 1-2 pocket holes pre-drilled and glue, I could not get the alignment perfect (or at all). My method was to use my figures and hold the rounded pieces into the face frame... Not ideal at all, but I couldn't figure how to hold, clamp, align, glue the pieces, hence the post here :-)
Definitely, I need help with the system that will hold, clamp, align, glue the pieces.
