Just make sure you have everything you need before you start. All your sandpaper, your flat surface and masking tape. Tape all 4 sides of the paper to the flat surface. Turn on a good movie (I used Fellowship of the Ring XE) and just do it yourself. Use the flat surface and all you do is push it forward on the sand paper and then pull it back. Use the same spot on the paper until it is done then move over 2" and continue. 220grit (HSF only) > 400grit (start CPU here) > 800 > 1000 > 1500/2000 for mirror shine. Rotate a quarter turn every time you move over 2".
When you are using the 220grit on the HSF and 400 on the CPU to start, you will notice when the base gets flat. Make a pass on the sand paper and look at the surface. If the streaks in a way where the whole flat surface was on the sandpaper at the same time (you will be able to tell trust me) it is flat.
Continue refining all the way through the grit progressions and always making sure to keep it flat
on the paper. It will have a tendency to want to raise up but as you go along you will figure out a way for you to personally keep the HSF/CPU flat on the sandpaper through the full motion pushing and pulling on the sandpaper. I have relatively long fingers so I always held the base of my TRUE. When the quarter turn was at a diangle, I still kept my fingers on the base. I was unable to hold it up high and keep it flat. Don't worry about damaging your $60 HS. It is built like a tank. It is more than twice as sturdy as a TT120. It feels like SOLID aluminum.
At 1000grit sprinkle
a little oil in the center of the paper. Dab it up so that there is not a puddle. Don't push through a puddle of oil. Just use a little to kind of lubricate the surface. It will help move across the fine grit surface.
It is not rocket science. You can't mess up because you are always going to have a guild...your flat surface. You don't have to press extremely hard because the sand paper does the work.
