Is it okay to rotate the heat sink 90° when lapping it? Wouldn't the a 90° rotation make you sand paper cutting acorss the fine lines you did before the rotation. See 1st you sandpaper to the north of the heatsink. Then when you rotate it 90° wouldn't you be sanding east or west of the heat sink? Wouldn't the fine lines cut each other?

I mean you will be sanding cutting across the line? Example:

1st:

Then next you will be sanding:

The 2 sides of sanding will not be together....but cutting each other.

Okay thanks. Would be doing that if i remove my heatsink again.

Owh means we must not sand untill mirror shine huh?

But if not mistaken it wouldn't affect much since if the surface isn't really mirror shine the metal touching each other would be very little and avoidable.

Glass as in the watter glass technique to see how the water spread?

I lapped my processor but abit hard since it's small and hard to hold and it's light so we can't expect it to apply force to the sandpaper itself.
