hahaha. I learned a neat trick today with an antenna, don't know exactly how its done. and I'm sure if the person who did it, see's this, he'll tell me to STFU lol. so lets just say, I think he might of used it for something illegal per say? and been caught in the act, therefore, causing him to drop it and run. or maybe he just can't find the location of the !$#* thing on his truck

If your school has a CNC lathe than it should have boxes of bolts laying around. I know ours did. If it doesn't than find a tap set (please tell me ya'll have that) and see what tap fits the hole the antenna goes into.
What are you going to use for the antenna? How long will it be? What will the final diameter of the antenna be?
Reason I ask is that CNC's put huge horizontal pressure on what it cuts. I had a 7in long piece of 4150 at .750in Dia that moved on me while, I was only having our HAAS SL-30 take .060 with a 55 degree carbide cutter. I couldn't use the tailstock cause I couldn't center drill the piece. I figure that is going to be your problem on the antenna. Its going to want to move toward you (if the cnc is turret style) or away from you (if it's like a tool room lathe).
There are many ways this can be countered. Cut the piece longer than needed and center drill and use the tailstock then just cut off the center drill and chamfer or do something on the end with a manual machine. If you are not wanting to make it anything to complicated than a manual lathe with a follower rest may be better.
Now that judgement is just from what was said in this convo so far. I am a machinist and will be glad to help you out if I can. Just PM me.
