The model
Two tapered tower levels with a plank texture, a pointed-arch door and windows, and a surrounding gallery with railing in between. At the top sits the Dutch cap with shingles on a turntable ring, which you can turn all the way around by hand.
As on real mills, the shaft is tilted slightly upward and runs in a bore with 0.4 mm clearance. The four lattice sails plug into the hub with wedge tenons, and a locking washer at the back holds the shaft. The sail cross turns freely, even when you just blow on it lightly.
Checked by calculation: the sail cross clears cap, tower and gallery freely in every position, and the cap turns freely in every position.
