Today Judy and I started building one, to gain two, pieces of furniture for the aft cockpit and cabins.These items, the seat bases and backs for the aft cockpit, also form the aft cabin lockers.
We measured, marked and cut out two panels for each side, a little oversize on some edges. Then they were fitted to the seat and cabin risers with plastic separators. This plastic is to to allow for removal on completion of the outside seat back to base joining fillet and tape.
Below are photos of the taping process and fitted panels.
