Lapping guide?

I remember seeing a guide a few months ago on a "new and improved" way to lap that was much easier. I believe it only required a couple grits of sandpaper and a whole lot less time... I can't find the thread I have tried seraching for it... could someone please point it out thanks!!!

well i used 600,800,1000,2000 grit.took me like 2 hours.
I'd link you to it, but I can't find it...

Anyways, the trick is to use 220, 400, 800 and 1500

People have a tendency to shy away from 220 and 400 because they're so rough, but they're a great way to get down to the copper portion of the IHS and flatten the surface! Grits above 400 are really intended for polishing, not flattening and if you use them right off the bat, you'll end up wasting a bunch of time and money on costly paper (polishing paper is more expensive than sanding paper)

So yeah, use 220 and 400 for sanding and anything above for polishing... I can personally lap an IHS or Heatsink's base to a flat shiny surface in 15-20 minutes
