Some fascinating windmill designs courtesy of the original artists and their publication or patent drawings. Scale and semi scale cad drawings are still in process and will be offered for sale when complete which will include both vertical and horizontal varieties. 2018’s model is of a 1899 BattleAx windmill based on a design found in the book “Homemade windmills of Nebraska 1899” Battle ax windmills are unusual. This particular windmill was designed to be mounted on a short tower on top of a building eliminating most of the tower and because it is non wind direction sensitive. The author makes mention of a furling mechanism but no other details are supplied. My model has 50mm diameter sails and they start rotating under light windpower. It is a very interesting windmill to watch.
