For me it was very educational as this was my first reg overhaul. If I may offer a couple of tips, read the manuals (I found the Voit manual easier to understand than the U.S. Divers), if you're not sure ask questions here on the forums. There are many great people here who will answer your questions. Its easier to ask questions and do it right than it is to screw it up and try to figure out what you did wrong. Don't be penny wise and pound foolish when it comes to parts. Rubber parts that are 50 - 60 years old, even if they work now may not work for long.
