  • Step by step

    I am new to the polishing hobby but have always wanted to do it. So after reading the caswell handbook thoroughly i had enough guts to attempt some polishing. I decided that i wanted to do my turbo housing for my truck. I took some pics from the beginning and i am going to keep posting them as time goes on. Maybe we can all learn from this? Maybe i just want to show off! LOL! Anyway here ya go!!

    This was the pic in the beginning with nothing done but some experimenting on the inlet. Stage 1

    This was a shot after i hit the housing with a dremel to knock down the casting lines and bumps. I also ground down the numbers. I think i want to keep the mitsubishi word. I don't know why but...?? Stage 2

    I think there will be more stage two to come. This seems to be the longest step. I need to find some sorta pointy bit to get in the recessed area? How do those bobs work?

    Felt Bobs

    The felt bobs mount on an electric drill. They work in much the same way as a buffing wheel. Apply compound to the bob in small applications, then polish, then re-apply.

    Also like buffing wheels, large size bobs cover more area, but turn at a lower speed.

      ok i am running into a problem. The recessed area that you see, i CANNOT get there! It's driving me nuts. I have tried the bullets with 80 grit stuck to it to try and smoothe it out for polishing. It just falls off the bob. I have tried it by hand but it's too small for me to get a good movement going. Help...
