| 説明 | This iron wheel is fitted to the main upright shaft (Its thrust bearing may be seen in the previous pic). The teeth are made from hard applewood and are designed to be easily replaceable. Indeed apple orchards were often planted near windmills for that purpose. The spur wheel drives four pairs of grindstones via small pinions (not visable) known as "nuts" |
