XI Have seen the latest drawing of the governor controlled fan speed. This is being worked at hard to provide a drive that also will not over speed the dynamo / many here are now belt driven! In its latest form The bottom pulley is spring loaded only and opens out to reduce drive ratio under the influence of the governor. | ||
