Here's a good machining project for the beginning and experienced machinist alike, a machinist's screw jack. This tool is useful for a variety of jobs, like leveling a part on the mill table and supporting work pieces so they do not chatter. Making this part will give experience in a lot of different machining processes, so it is a fantastic first project. Links to the prints below:
