The first head was absurd (top). A hand wrapped electro magnet that worked so poorly I had to have counter weights on the opposite side of the brush. But it made cool strokes. Unfortunately it only lasted a couple of weeks before I replaced it.
The second head was awesome (middle). Completely hand made primarily with wood, this robotic head painted for over a year without failure. I just retired it today and replaced it with a new head. Its only problem was that it would overheat and loose electromagnetic strength the longer it was in operation.
The third head was acceptable (bottom). It worked O.K., but didn’t have the style of the second. Also, it would jam occasionally. That is why when the fourth robotic head was constructed, I replacedis one with it instead of the second.
The fourth robotic head (unpictured), looks very similar to the fifth robotic head which is pictured below. It was designed and fabricated by Jacobus McKenzie. It does a majority of my paintings these days.
