First attemp at lapping HSF

[Kryten]

I had my first go a lapping a HS last night, I used my stock Intel Celeron one, I spent an hour lapping using 1000, 1200,1500 and 2000 it turned out allright but not a mirror shine like I expected, something I did find interesting was that the 2000 needed to nearly worn out before I was getting any kind of shinny results.
I am expecting to much or do I need to use additional products to get the mirror shine I have seen posted here before.

Shadow had posted something concerning the useage of, all things, Crest toothpaste, for polishing the hsf after lapping.

This was posted in either the General Disscussion or here in Cooling, can't remember which.

Supposedly works quite well..... Go digging and try to find it. You'll have to go back a page or three...I'll look for it too, and post the location when I find it (if you don't first....=) )

I do vaugely remember a post like that, if you find it that would be good if I get chance I will go search for it.
Thanks Mr B

You don't need a mirror finish. As long as the base is flat and smooth, you will see diminishing returns for the effort necessary to reach mirror finish. Grease it up and take it for a spin.

Shadow posted a pic with the thread...didn't load for me when I just went back....curious....

It's kinda neat going back thru the topics that far....I think a lot of "Oh wow...I forgot about this one!" when I do.

Hope it helps!

I wasn't overly concerned because it seems a damn site more flat and very very few minor scratches as apposed to the rough factory finish, I was just more curious as to how the mirror finish was achieved I personally felt there would be little extra benifit from it.

thanks a heap Mr B will look now.
ok I couldn't get the piccy to load either but I remember what it looked like.
was more curious about how he applied the toothpaste from what I can gather it was just with rag and compound no flat surface.

I have been busy with the tissues and toothpaste (colgate fluoriguard) it has improved a little but still not mirror like.
Although I am getting a reasonable reflection off things maybe its just the angle the photos were taken on...

If I remember correctly, he just used a dab of toothpaste and worked it with a rag for about an hour while watching TV. He also said that a larger amount produced worse results.

I tried varying amounts but didn't seem to make much difference maybe its the toothpaste type cant buy the one he mentioned in Australia.

I used a metal polish for car wheels as a final. When I lapped my heatsink, I never got a perfect "mirror" finish either. Sounds like what you've done should work great. Anything is better than nothing in my opinion.
