I am trained in and have worked as an Electrical Engineer, but I have a soft spot for machinery. I have several old tractors and trucks that I maintain. On another thread, someone was laughing at my old, 25 year old pickup, because it only makes 175 HP, but the truth is, that is more than sufficient for me, and I like to keep it going as sort of a rolling museum of transportation technology. So, I spend alot of time underneith it with a pile of wrenches and dirty rags. Same for my tractors. I'm also a certified welder (my first career, long, long ago) and I own a metal fabrication shop. It's not a commerical operation, more of a hobby. In the near future, I hope to combine my electronics and mechanical hobbies, and make a CNC plasma cutting table. I have all the bits, just need to make the time to put it all together.
