Windmill Restoration March 2009

Bob fabricates the sails. The ‘whips’ are 9000mm long, made from steel channels that taper from 300mm to 125mm over the length.

Each of the nine sail bars are 40mm x 40mm box section, set on a gradual curve, starting at 21.5 degrees at the root and finishing at 6.5 degrees at the tip. Each sail weighs 664kg, and that’s without the shutters!

We have the 14 sections of rack, (the mechanism which the fantail turns the cap by) profiled from 30mm steel, and Bob makes a ‘lantern’ pinion to match.
