Nice work, Herb. I especially like the cedar ones. It's a shame you're going to stop making them but no project is worth risking your life over. I always used one (right) hand when dealing with high voltages. It's more dangerous to get a shock from one hand through to the other because the path goes closer to your heart. Even the left is worse than the right, when using one hand. I got a shock in college where the TV flyback transformer arced to my finger, the instructor came around sniffing and asked if anyone could smell anything. Smelled like burning hair. I had a hole in my finger about a 1/16th wide by an 1/8th deep, fully cauterized and hard. I hadn't touched a wire or connection, just came too close and it arced. Because an adult male has dry calloused skin, the resistance is quite high but a high enough voltage can overcome that. When you're working with liquids that makes it all the more dangerous by lowering your resistance. It only takes a few milliamps through your heart and it can be fatal.
