I got the removable wing done! I’ll try to cover it as best as I can in this post, and feel free to ask questions to clear any confusion up. The wing is held in place with 6 small dowels, each about 5cm long, 3 on each side. First, I cut out some plywood doublers to go on the inside of the fuse:
I then used CA glue to attach them.
Then, I took two strips of coroplast and weakly hot glued them to the plywood doublers after aligning them to the top border of the fuselage. Using this bond, I passed 3 dowels through each strip and broke the hot glue bond, leaving it like this:
I then ran hot glue along the top of these coroplast strips and attached the wing to this bond, making sure to align the wing as perfectly as possible. After pulling out the dowels and removing the wing, these coroplast strips were attached to the fuselage, in a perfectly aligned position that accounts for any error in the fuselage or wing build:
The two strips aren’t exactly next to each other, but that wasn’t necessary for the perfect alignment. After marking out the position of these strips with pencil, I removed them and cut out a slit in the wing where the strips were. I inserted another two pieces of coroplast into the wing, pushing them in fully and joining them with CA glue.
I added plywood doublers on the inside of this too, and used CA glue to attach dowels for additional compressive stiffness. I weakly glued down the wing with this structure inside to the fuselage, aligning it as perfectly as I could again. Once the wing was glued down, I passed sharp dowels through the fuselage mounting holes and plywood doublers to mark where they would go through in the mounting structure on the wing. I then made holes where the dowels made marks, leaving this on the bottom of the wing:
The holes were perfectly aligned with those in the fuse, so I could use the six small 5cm dowels to attach the wing to the fuselage, 3 on each side:
