When doing the CPU, if provided when you purchased it, use the little plastic cap that goes over the back of the chip; otherwise, when finished lapping the CPU, just blow the pin side out real good with some compressed air. Also, you can use a magnifying glass to inspect for any particles.
Thanks for the tips! I'm going to use that cap that comes with it then.

And I think I'm going to practice on my P4 S478 (3,0 prescott) & NB-CoolScraper 120 (rev2.0) first

I'm wondering how you can create a flat surface by moving the big Infinity over the sandpaper... any experience-tips about that would be great!
