equipment used.Okay, here are the pictures of the equipment i Used. There are 4 pads, one is aluminum oxide which is the coarse sand paper the other two are .3m and .1m papers and the black thing is a buffing pad. Unfortunately I did not think to take pictures during the process to show the finish, but the copper looked almost as shiney as chrome that has just been polished. Obviously I started with the low course to remove dirt grit and impurities, sanding in a figure 8 motion. then I used the .3m to rectify the surface, then the .1m to further rectify the surface. The buffing pad was used to smooth out the micro valleys in the heat sink. After which I used a microscope and light system from a pace kit to check the surface. I could still see some imprefections in it which I tried to rctify but could not entierly make it perfect after about 30 minutes of buffing. You can prolly see the top of one of my Marines head. This is just the commentary, I was going to upload the pictures right now at work but these computers are ran by NMCI(navy marine corps intranet) aka: Nazi Marine Corps Intranet, and its not mounting my phone like it used to.
