Wow, that's an amazing tool. Thanks for the link. I don't do woodworking, but it's always facinated me. I've done minor stuff when I was helping my dad or working around the house such as door jams or slotting contours to make things fit. I do however think my dad and several people at work would be greatly interested in this! My supervisor, our network administrator, does some very finely detailed work, such as cutting out rose shapes to put into hand made jewelery boxes, or actual petals to mount on top.

Back on topic I used a kit (http://www.easypckits.com/) to lap my heatsink and it worked great. I had to redo the last 2 sheets of fine sandpaper because the polished side was so smooth that the copper that it ground off scarred the bottom again. So I had to rinse the paper a few times to get that final shine and not scratch it up. I'll see if my girlfriend can bring her camera and cable so I can upload a good picture of it for this post. Like you said, a "light touch", but I can read the fine print in the reflection and I've not cheated by polishing it with a polish! I did have to use the 400/600/800 sheets a few times and literally use every square inch of each sheet to get down to a fairly flat surface. The Tuniq Tower120 is a top notch air cooler, but the copper footing was horrible. I would have used a grinder like that to start off with if I had realized just how badly it was off, and that's no joke!
