Not to be a nag, but don't glue that anchor deck in place until you've rigged the lower attachments of the mainstay securely through both the anchor deck and the main deck. You will have a very hard time doing it after the anchor deck is permanently in place and the mainstay has to be well secured because it will take a major part of the collective strain from the collective rigging running fore and aft. Check your plans carefully. I believe the mainstay parts run fair through both the anchor deck and the main deck and are secured to the stem inboard.
