This windmill is much simpler than the post windmill. It is constructed mainly from the new style Junior Meccano with motorisation provided by a few traditional metal pieces. The sails rotate thanks to the clockwork motor and the noise and motion held the interest of my seven month old daughter and our cats.
Construction of this simple windmill is easy and should be straight forward from the illustrations. It should be noted that the sails and their mounting plate are not fixed to the drive shaft. The four strips that support the arms grip the driving axle and provide a simple friction clutch assembly. It sounds horrible, but it works remarkably well giving a nice smooth speed up when power is applied.
This is the front view of the windmill. Some of the mechanics around the motor are visible.
Here is the rear view of the windmill. The belt drive to the sails is visible here.
Finally, a side view of the mill. All three pictures together should provide enough information for somebody to rebuild the majority of this model.
