Well, it is Tuesday again, which means I have to come up with a tip. If you have any suggestions, please feel free to post them. Todays tip is about pitting. There can be many, many problems that cause pitting and it seems to be the biggest problem when electropolishing. One of the causes for pitting is too low water. The pits are in bright star shapes, known as phosphoric pits. To remedy this, you may just need to add water to your bath.
