Fourth: in the small end a 1⁄4-inch hole was bored at the centre, about an inch deep.
Fifth: the blades were tapered in thickness from 1⁄2-inch at the small end to 3⁄16-inch at the wide end, the tapering being done on one side only, that away from the wind, the side facing the wind being perfectly flat.
Sixth: dowel pins were glued securely into the holes in the hexagonal block and into the blades, the latter being turned on the dowels at an angle of about 30 degrees—1⁄3 a right angle—from the front face.
Seventh: after the glue had hardened over night, the whole mill was painted, special attention being given to covering the joint where the glue held, to prevent the rain from loosening it.
Eighth: two pieces of 1⁄4-inch white wood were cut out to the form shown at b. These were fastened to the square piece c by two small bolts.
The wide ends of the vanes were spread and fastened by two small strips of white wood, by brads as shown.
Ninth: last came the locating of the centre of gravity, after the mill had been attached by a ten-penny flat-head wire nail. The pivot was made of a similar nail into the standard, as on previous wind vanes.
