I have an old Unimat lathe from the 1960's, i have made many parts with it like pulleys and ignition coils. First tip i would start with Aluminum over metal or brass it's easier to use second choose your stock a little thicker and at least 40% longer than the part you want to create, the reason for the stock being thicker is you want to turn the stock down to size so you can reduce and get it as perfectly round as possible, put some stock in the machine and you will see what i mean by how out of round or wabble it has you will want to remove that wabble. After this it's a lot of practice but you will be amazed at how quick you will pick it up, i hope this helps, later i will post a pick of some of the parts i made if you like. you can also check a great site called mini-lathe .com awsome site for the beginner. The parts below were made for a 1/16 scale Mustang engine but the same can be done for 1/24 scale sorry for the bad pic first day with the new camera.
