AC power controller was fabricated by myself with making use of Wonder Kit PC-16A printed circuit plate. This kind of semiconductor circuitry is indispensable for precise rotation control of a grinder and sharpener devices.

The air duct fixation was performed in VW 1302 Super Beetle engine room that was necessary but left undone for long time, because it fell down so often after a long driving. As the duct was set in different way from the original design because of a cooler cooler compressor equipment retrofit, that caused some tendency to fall down, remembering the past, the duct was not found from the beginning. Heat and vibration must have brought this inconvenience. Now, such kind of anxiety would be eliminated thoroughly, butyl rubber self fusing tape applied the portion and Ju-Billie band would make the fixation surer from now. Hitting and slipping noise discerned from outside that caused by fallen duct and crank polley resembles that caused by lack of lubrication grease in the generator main shaft supporting bearings.
