Default Machining a supercharger pulley

Ok well in college im majoring in mechanical engineering and we have to use a lathe for one of our labs. I asked the teacher if we could bring things and use the lathe. He doesn't care. So would there be any problems with machining down the supercharger pulley? What size would I want to make it? Would I need different bearings? Would I need to make another pulley smaller or bigger?

I did this to my old S/C pulley. There's not enough meat to make it equiv to a 178 or similar. What I did was get a 178, and machine the s/c pulley diameter down 2mm. The numbers worked out to be a little bit stronger than a 181. You can find the numbers and more information than you want in my thread "Of long posts and superchargers". For what it's worth, I'm running a 185 now...

Hello. I believe that your teacher is right. You can take a tool of any size. Teachers are people who know everything in their own industry. I am a teacher in the humanitarian industry. I ask my students to write a lot of papers that they buy on the service about which you can read more, that is a service on which you can buy essays, dissertations etc... I know that they are cunning, but this is the essence of an smart person.
