I have a South Bend Heavy 10 that was made circa 1981. I had to go through it, clean and replace all the wicks, there were a few broken gears that needed replacing. I reviewed the book, it is very detailed with easy to follow step by step instructions and they helped me understand how the machine is made and maintained. I highly recommend getting the full set along with the book, if you're not sure if you can service the lathe yourself you can't go wrong.
