Inception Top

I apologize this isn't a complete Instructable I completed this in an afternoon as a christmas gift for a friend of mine. The pictures are in order of how I went about making it. I basically put a 2" diameter chunk of aluminum onto my wood lathe... yes my wood lathe (I don't actually recommend anyone do this since it probably isn't the safest thing, but hey it worked for me and i've done it again since soooo yeah). I used my turning tool that has a carbide bit with the accompaniment of cutting oil. I approached it very slowly and just turned away.
