Hello Ralph, a technically simple and solid device, somehow the power transmission mechanism reminds me of the time of the locomobile with its transmissions. That's when I suddenly noticed how far-reaching the drive via a shaft had changed the applications, especially in agriculture. The nice thing about the picture and film is that the eyes, in the truest sense of the word, can help with thinking in a meaningful way. Like a "drive technique" in telepathy. My best regards, Henry
